'''''Big Brother''''' is a [[Reality television#Reality competition or game shows|reality competition]] television franchise created by [[John de Mol Jr.]], first broadcast in the Netherlands in 1999 and subsequently syndicated internationally<ref name="Nordicom 1">{{cite web|url=http://www.nordicom.gu.se/sites/default/files/kapitel-pdf/42_011-022.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.nordicom.gu.se/sites/default/files/kapitel-pdf/42_011-022.pdf |archive-date=9 October 2022 |url-status=live|title=New Media, New Options, New Communities?|author=Drotner, Kirsten|publisher=Nordicom|type=PDF|access-date=23 May 2014}}</ref> beginning in 2000. The show features contestants called "housemates" or "HouseGuests" who live together in a specially constructed house that is isolated from the outside world. The show has been cited as having had widespread influence on the status of television and celebrity.<ref>{{Cite news |last=Saner |first=Emine |date=2018-09-20 |title=How Big Brother's unvarnished underdogs changed TV |url=https://www.theguardian.com/tv-and-radio/2018/sep/20/how-big-brothers-unvarnished-underdogs-changed-tv |access-date=2025-07-15 |work=The Guardian |language=en-GB |issn=0261-3077}}</ref>

The name is inspired by [[Big Brother (Nineteen Eighty-Four)|Big Brother]] from [[George Orwell]]'s novel ''[[Nineteen Eighty-Four]]'', and the housemates are continuously monitored during their stay in the house by live television cameras as well as personal audio microphones. Throughout the course of the competition, they are voted out of the house  (usually on a weekly basis) until only one remains and wins the cash prize.

{{As of|2023|8|5}}, there have been 508 seasons of ''Big Brother'' in over 63 franchise countries and regions. English-language editions of the program are often referred to by its initials ''BB''.<ref>{{cite web|url=http://www.channel5.com/shows/big-brother/episodes?season=15706http:/www.channel5.com/shows/big-brother/episodes?season=15706|title=Celebrity Big Brother|publisher=Channel 5}}</ref>

At regular intervals, the housemates privately nominate a number of their fellow housemates whom they wish to be evicted from the house.<ref>{{cite web|url=http://www.endemol.com/programme/big-brother|title=Big Brother|publisher=[[Endemol]]|access-date=23 May 2014}}</ref> The housemates with the most nominations are then announced, and viewers are given the opportunity to [[televoting|vote via telephone]] for the nominee they wish to be evicted or saved from eviction. The last person remaining is declared the winner.

Some more recent editions have since included additional methods of voting, such as voting through social media and smartphone applications. Occasionally, non-standard votes occur, where two houseguests are evicted at once or no one is voted out. In the earlier series of ''Big Brother'', there were 10 contestants with evictions every two weeks. However, the British version introduced a larger number of contestants with weekly evictions. Most versions of ''Big Brother'' follow the weekly eviction format, broadcast over approximately three months for 16 contestants.

The contestants are required to do housework and are assigned tasks by the producers of the show (who communicate with the housemates via the omnipresent authority figure known to them only as "Big Brother"). The tasks are designed to test their teamwork abilities and community spirit. In some countries, the housemates' shopping budget or weekly allowance (to buy food and other essentials) depends on the outcome of assigned tasks.

== History ==

=== Name ===
The term ''Big Brother'' originates from [[George Orwell]]'s novel ''[[Nineteen Eighty-Four]],'' with its theme of continuous oppressive surveillance.<ref name="Nordicom 1" /> The program also relies on other techniques, such as a stripped back-to-basic environment, evictions, weekly tasks and competitions set by ''Big Brother'', and the "Diary Room" (or "Confession Room") where housemates convey their private thoughts to the camera and reveal their nominees for eviction.

=== Creation ===
The first version of ''Big Brother'' was broadcast in 1999 on [[Veronica (TV channel)|Veronica]] in the [[Big Brother (Netherlands)|Netherlands]]. In the first season of ''Big Brother'', the house was very basic. Although essential amenities such as running water, furniture, and a limited ration of food were provided, luxury items were often forbidden. This added a [[survivalist]] element to the show, increasing the potential for social tension. Nearly all later series provide a modern house for the contest with a Jacuzzi, sauna, VIP suite, [[loft]], and other luxuries.

=== International expansion ===
The format has become an international TV franchise. While each country or region has its own variation, the common theme is that the contestants are confined to the house and have their every action recorded by cameras and microphones and that no contact with the outside world is permitted.

Most international versions of the show remain quite similar: their main format remains true to the original [[fly on the wall]] observational style with an emphasis on human relationships, to the extent that contestants are usually forbidden from discussing nominations or voting strategy. In 2001, the [[Big Brother (American TV series)|American version]] adopted a different format since the second season, where the contestants are encouraged to strategize to advance in the game; in this format, the contestants themselves vote to evict each other and a Jury of Evicted contestants vote for the winner.  Occasionally, individual game twists and format changes may allow for some viewer voting, usually to give a game advantage to the Housemates selected by the viewer vote. ''[[Big Brother Canada]]'', introduced in 2013, also follows the American format, while the Australian series also used an American-styled format when the series was rebooted in 2020, with the winner being decided by Australia's vote among the Finalist.

Other international versions have included aspects of the American format. In 2011, the [[Big Brother (British TV series)|British version]] controversially adopted the discussion of nominations before reversing this rule after a poll by ''Big Brother'' broadcaster [[Channel 5 (UK)|Channel 5]].<ref>{{cite web|url=http://www.bbspy.co.uk/bb13/features/0608/poll-big-brother-2012-housemates-discuss-nominations|title=Poll: Should housemates be able to talk nominations?|author=Scott, Matt|date=8 June 2012|publisher=BBSpy|access-date=23 May 2014|archive-date=7 March 2014|archive-url=https://web.archive.org/web/20140307174755/http://www.bbspy.co.uk/bb13/features/0608/poll-big-brother-2012-housemates-discuss-nominations|url-status=dead}}</ref>

== Reception ==

=== Overview ===
From a sociological and demographic perspective, ''Big Brother'' allows an analysis of how people react<ref>{{Cite web|url=https://www.news.com.au/entertainment/tv/psychologist-behind-big-brother/news-story/e193d00b9cc9a23be9917232d1a2e20c|title=Meet the psychologist behind Big Brother |publisher=News.com.au|access-date=19 March 2019}}</ref> when forced into close confinement with people outside of their [[comfort zone]] (having different opinions or ideals, or from a different socioeconomic group). The viewer has the opportunity to see how a person reacts from the outside (through the constant recording of their actions) and the inside (in the Diary or Confession Room). The Diary Room is where contestants can privately express their feelings about the game, strategy and the other contestants. The results range from violent or angry confrontations to genuine and tender connections (often including romantic interludes).

In 2011, Brazilian [[sociologist]] Silvia Viana Rodrigues wrote a thesis at the [[University of São Paulo]] analyzing reality shows as spectacles that proliferate [[ritual]]s of suffering.<ref>{{Cite thesis |last=Viana |first=Silvia |date=December 18, 2012 |title=Rituais de Sofrimento |url=https://www.teses.usp.br/teses/disponiveis/8/8132/tde-18122012-130446/pt-br.php |access-date=December 24, 2023 |website=Teses e Dissertações – USP|doi=10.11606/T.8.2011.tde-18122012-130446 |doi-access=free }}</ref> She analyzes such rituals in various cultural products from [[Hollywood, Los Angeles|Hollywood]] and [[Television in Brazil|Brazilian television]], with special attention to ''[[Big Brother Brasil]]''. When investigating the openly eliminatory and cruel face of the game,<ref>{{Cite web |last=Michael |first=Andréia |date=March 21, 2010 |title="'Big Brother' não é cultura, é um jogo cruel", diz Boninho |url=https://www1.folha.uol.com.br/fsp/ilustrad/fq2103201005.htm |access-date=December 24, 2023 |website=Folha de SP}}</ref> Silvia Viana points out that such characteristics are liable to be entertainment with great and crucial public engagement because such processes of elimination, [[competition]], exclusion, the affirmation of the [[Bellum omnium contra omnes|war of all against all]], of self-management and personal self-control through [[Emotional intelligence|socio-emotional skills]], [[entrepreneurship]], the [[banality of evil]], the naturalization of [[torture]], the "battle for survival" logic and the incorporation of [[Nazism|Nazi]] language and elements are already part of contemporary social life, especially in the context of work under [[neoliberalism]].<ref>{{Cite web |last=Rüdiger |first=Francisco |date=2014 |title=Rituais de sofrimento ou teatro do sucesso sem virtude? |url=https://revistaecopos.eco.ufrj.br/eco_pos/article/view/1295 |access-date=December 24, 2023 |website=Revista Eco-Pós |issn=2175-8689}}</ref> The thesis was later published as a book.<ref>{{Cite book |last=Viana |first=Silvia |title=Rituais de Sofrimento |publisher=Boitempo |year=2012 |isbn=978-85-7559-309-7 |edition=1st |location=São Paulo, Brasil |language=Portuguese}}</ref>

The show is notable for involving the Internet. Although the show typically broadcasts daily updates during the evening (sometimes criticized by viewers and former contestants for heavy editing by producers),<ref>{{cite journal | url=http://stakeholders.ofcom.org.uk/binaries/enforcement/broadcast-bulletins/obb110/issue110.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://stakeholders.ofcom.org.uk/binaries/enforcement/broadcast-bulletins/obb110/issue110.pdf |archive-date=9 October 2022 |url-status=live | title=Complaint by Ms Dawn Blake | author=Blake, Dawn | journal=Ofcom Broadcast Bulletin | date=27 May 2008 | issue=110 | type=PDF}}</ref> viewers can also watch a continuous feed from multiple cameras on the Web in most countries. These websites were successful, even after some national series began charging for access to the video stream. In some countries, Internet broadcasting was supplemented by updates via email, [[Wireless Application Protocol|WAP]] and SMS. The house is shown live on satellite television, although in some countries there is a 10–15 minutes delay to allow libelous or unacceptable content (such as references to people not participating in the program who have not consented to have personal information broadcast) to be removed.

Contestants occasionally develop sexual relationships; the level of sexual explicitness allowed to be shown in broadcast and Internet-feed varies according to the country's broadcasting standards.

=== Isolation ===
''Big Brother'' contestants are isolated in the house, without access to television, radio, or the Internet. They are not permitted routine communication with the outside world. This was an important issue for most earlier series of the show. In more-recent series, contestants are occasionally allowed to view televised events (usually as a reward for winning at a task). In most versions of the program, books and writing materials are also forbidden, although exceptions are sometimes made for religious materials such as the Bible, [[Tanakh]] or the [[Qur'an]]. Some versions ban all writing implements, even items that can be used to write (such as lipstick or eyeliner). Despite the housemates' isolation, some contestants are occasionally allowed to leave the house as part of tasks. Contestants are permitted to leave the house in an emergency.

News from the outside world may occasionally be given as a reward. Additionally, news of extraordinary events from the outside world may be given to the Housemates if such information is considered important, such notable past examples include that of national election results,<ref>{{Cite web|url=https://www.youtube.com/watch?v=R9QD2hSPNT0| archive-url=https://ghostarchive.org/varchive/youtube/20211123/R9QD2hSPNT0| archive-date=23 November 2021 | url-status=live|title=Julie tells Big Brother houseguests that Trump won.

Contestants have regularly scheduled interactions with the show's host on eviction nights. Throughout each day, the program's producer, in the "Big Brother" voice, issues directives and commands to contestants. Some versions of the show allow private counselling sessions with a psychologist. These are allowed at any time and are often conducted by telephone from the Diary Room.

Due to the intelligibility of certain languages across several nations, it has been possible to make regional versions of ''Big Brother''. All of these follow the normal ''Big Brother'' rules, except that contestants must come from each of the countries in the region where it airs: ''[[Big Brother (Albanian TV series)|Big Brother Albania]]'' of [[Albania]] and [[Kosovo]], ''Big Brother Angola e Moçambique'' of [[Angola]] and [[Mozambique]], ''[[Big Brother Africa]]'' of Africa (includes Angola, [[Botswana]], [[Ethiopia]], [[Ghana]], [[Kenya]], [[Liberia]], [[Malawi]], Mozambique, [[Namibia]], [[Nigeria]], [[Rwanda]], [[Sierra Leone]], South Africa, [[Tanzania]], [[Uganda]], [[Zambia]] and [[Zimbabwe]]), [[Big Brother: The Boss|''Big Brother:'' الرئيس]] of the Middle East (includes [[Bahrain]], [[Egypt]], [[Iraq]], [[Jordan]], [[Kuwait]], [[Lebanon]], [[Oman]], [[Saudi Arabia]], [[Somalia]], [[Syria]] and [[Tunisia]]), ''[[Gran Hermano (Pacific)|Gran Hermano del Pacífico]]'' of South America (includes Chile, [[Ecuador]] and [[Peru]]), ''[[Big Brother (Norwegian and Swedish TV series)|Big Brother]]'' of Scandinavia (includes [[Norway]] and Sweden) and ''[[Veliki brat]]'' of the Balkans (includes [[Serbia]], [[Montenegro]], [[Croatia]], [[Bosnia and Herzegovina]] and [[North Macedonia]]). The British version of the show previously accepted Irish applicants, however the [https://www.bigbrother.com/downloads/BIG%20BROTHER%202023%20TERMS%20AND%20CONDITIONS%20FINAL.pdf terms and conditions] of ITV2's reboot state you must reside in the UK.

On the other hand, some countries have multiple franchises based on language. ''[[Bigg Boss]]'' of India has the most regional-based versions [[Hindi]], [[Marathi language|Marathi]], [[Tamil language|Tamil]], [[Bengali language|Bengali]], [[Telugu language|Telugu]], [[Kannada]] and [[Malayalam]] language versions; Canada has French- and English-language versions; and the United States has English- and Spanish-language versions of the show.

The Pakistani television program ''[[Tamasha (TV series)|Tamasha]]'' recently became a part of the franchise. Initially produced by [[ARY Digital]], a Pakistani TV channel, the reality show's first season garnered significant success and audience engagement, with its different twists and tasks being the main concept of the show. During its second season, the show officially adopted the original format of ''Big Brother''. As of 2023, it stands as the sole franchise of the ''Big Brother'' format in [[Pakistan]], with the show being conducted exclusively in the [[Urdu|Urdu language]].

=== Twists involving single franchises ===

==== Multiple areas and houses ====
In 2001, ''[[Big Brother (Dutch TV series) season 3|Big Brother 3]]'' of the Netherlands introduced the "Rich and Poor" concept, in which the house is separated into a luxurious half and a poor half, and two teams of housemates compete for a place in the luxurious half. The Dutch version continued this concept to the end of its [[Big Brother (Dutch TV series) season 4|fourth season]]. Other versions later followed and introduced a similar concept, of which some have their own twists: [[Big Brother Africa|Africa]] (in [[Big Brother Africa season 5|2010]], [[Big Brother Africa season 6|2011]], [[Big Brother Africa season 7|2012]] and [[Big Brother Africa season 8|2013]]), [[Big Brother Albania|Albania]] (in [[Big Brother (Albanian TV series) season 3|2010]]), [[Big Brother (Australian TV series)|Australia]] (in [[Big Brother (Australian TV series) season 3|2003]] and [[Big Brother (Australian TV series) season 10|2013]]), [[Big Brother (Serbian TV series)|Balkan States]] (in [[Big Brother VIP (Serbian TV series) season 4|VIP 2010]] and [[Big Brother (Serbian TV series) season 4|2011]]), [[Big Brother Brasil|Brazil]] ([[Big Brother Brasil 9|2009]]–present), [[Big Brother Canada|Canada]] ([[Big Brother Canada season 1|2013]]–[[Big Brother Canada season 12|2024]]), [[Big Brother (Danish TV series)|Denmark]] (in [[Big Brother (Danish TV series)|2003]]), [[Big Brother (Finnish TV series)|Finland]] (in [[Big Brother (Finnish TV series) season 5|2009]] and [[Big Brother (Finnish TV series) season 10|2014]]), France (in [[Secret Story (French TV series) season 3|2009]], [[Secret Story (French TV series) season 5|2011]]–[[Secret Story (French TV series) season 11|2017]]), [[Big Brother (German TV series)|Germany]] (in [[Big Brother (German TV series) season 4|2003]], [[Big Brother (German TV series) season 5|2004–05]], [[Big Brother (German TV series) season 6|2005–06]], [[Big Brother (German TV series) season 8|2008]], [[Big Brother (German TV series) season 9|2008–09]] and since [[Promi Big Brother season 2|Celebrity 2014]]), [[Big Brother (Greek TV series)|Greece]] (in [[Big Brother (Greek TV series) season 3|2003]]), [[Bigg Boss|India]] (in [[Bigg Boss (Hindi TV series) season 6|2012]] and [[Bigg Boss (Hindi TV series) season 7|2013]]), [[Big Brother (Israeli TV series)|Israel]] (in [[Big Brother (Israeli TV series) season 2|2009]]), [[Grande Fratello|Italy]] (in [[Grande Fratello season 6|2006]] and [[Grande Fratello season 7|2007]]), [[Big Brother (Norwegian TV series)|Norway]] (in [[Big Brother (Norwegian TV series)|2003]]), [[Pinoy Big Brother|Philippines]] (in [[Pinoy Big Brother: Double Up|2009]], [[Pinoy Big Brother: Teen Clash 2010|Teen 2010]] and [[Pinoy Big Brother: Unlimited|2011]]), [[Big Brother (Polish TV series)|Poland]] (in [[Big Brother (Polish TV series) season 3|2002]]), [[Big Brother (Portuguese TV series)|Portugal]] (in [[Big Brother VIP (Portuguese TV series)|VIP 2013]] and [[Secret Story 6 (Portuguese season)|2016]]), [[Big Brother (Slovak TV series)|Slovakia]] (in [[Big Brother (Slovak TV series)|2005]]), [[Big Brother (Slovenian TV series)|Slovenia]] (in [[Big Brother (Slovenian TV series) season 2|2008]], [[Big Brother (Slovenian TV series) season 3|2015]] and [[Big Brother (Slovenian TV series) season 4|2016]]), [[Big Brother (Norwegian and Swedish TV series)|Scandinavia]] (in [[Big Brother (Norwegian and Swedish TV series)|2005]]), [[Big Brother (South African TV series)|South Africa]] (in [[Big Brother Mzansi season 1|2014]]), [[Gran Hermano (Spanish TV series)|Spain]] (in VIP 2004, [[Gran Hermano (Spanish TV series) season 10|2008]], [[Gran Hermano (Spanish TV series) season 11|2009–10]] and [[Gran Hermano (Spanish TV series) season 12|2010]]), [[Big Brother (British TV series)|United Kingdom]] (in [[Big Brother (British TV series) series 3|2002]], [[Celebrity Big Brother (British TV series) series 5|Celebrity 2007]], [[Big Brother (British TV series) series 9|2008]], [[Celebrity Big Brother (British TV series) series 11|Celebrity 2013]] and [[Big Brother (British TV series) series 17|2016]]), [[Big Brother (American TV series)|United States]] ([[Big Brother 11 (American season)|2009]]–present) and [[Bigg Boss (Tamil TV series)|Tamil Nadu, India]] ([[Bigg Boss (Tamil TV series) season 7|2023–24]])

In 2011–12, the [[Gran Hermano (Argentine TV series) season 7|seventh Argentine series]] added ''La Casa de al Lado'' ("The House Next Door"), a smaller, more luxurious house which served multiple functions. The first week it hosted 4 potential housemates, and the public voted for two of them to enter the main house. The second week, two pairs of twins competed in the same fashion, with only one pair allowed in. Later, the 3rd, 4th and 5th evicted contestants were given the choice of staying on their way out and they competed for the public's vote to reenter the house. Months later, after one of the contestants left the house voluntarily, the House Next Door reopened for four contestants who wanted to reenter and had not been in such a playoff before. The House Next Door was also used in other occasions to accommodate contestants from the main house for limited periods of time, especially to have more privacy (which of course could be seen by the public).{{citation needed|date=October 2017}}<!-- WP:RS needed; removed link to WP-->

The [[Big Brother Brasil 9|ninth Brazilian season]] featured the "Bubble": a glass house in a shopping mall in Rio de Janeiro where four potential housemates lived for a week. Later in the season, a bubble was built inside the Big Brother house, with another two housemates living in it for a week until they were voted in and the glass house dismantled. The Glass House was reused in the [[Big Brother Brasil 11|eleventh season]], featuring five evicted housemates competing for a chance to join the house again, and in the [[Big Brother Brasil 13|thirteenth season]], with six potential housemates competing for two places in the main house. A dividing wall from the ninth season was reused in the [[Big Brother Brasil 14|fourteenth Brazilian season]], when mothers and aunts of the housemates entered for [[International Women's Day]] and stayed in the house for 6 days, though they could not be seen by the housemates. Every season brings back the glass house. Some editions also featured an all-white panic room, where contestants were held until one of them decided to quit the show.

In the [[Big Brother Canada (season 4)|fourth English-Canadian season]], two house guests were evicted and moved into a special suite where they were able to watch the remaining house guests. A week later, the houseguests were required to unanimously decide which of them to bring back into the house.

==== Evil Big Brother ====
In 2004, the [[Big Brother (British TV series) series 5|fifth British series]] introduced a villainous ''Big Brother'' with harsher punishments, such as taking away prize money, more difficult tasks and secret tricks. This concept has also been used in Australia, Belgium, Bulgaria, Croatia, Finland, Germany, Greece, Italy, the Netherlands, South America,{{clarify|date=November 2017}} [[Scandinavia]],{{clarify|date=November 2017}} Serbia, Spain, Thailand, Philippines and Mexico.

==== Twin or triplet housemates ====
In 2004, the [[Big Brother 5 (American season)|fifth American season]] introduced twins who were tasked with secretly switching back and forth in the house; they were allowed to play the game as individual house guests after succeeding at the deception for four weeks. This twist was reused in the [[Big Brother 17 (American season)|seventeenth American season]] without the deception element – the pair simply needed to survive five weeks without being ''evicted''. HouseGuests who discovered this twist could use the twins to their strategic advantage.

This twin or triplet twist was used in several countries. Some made modifications to this twist; others have had twins in the house together without this element of secrecy. The following are the countries that have featured twins or triplets: Australia (in [[Big Brother (Australian TV series) season 5|2005]]), Germany (in [[Big Brother (German TV series) season 6|2005–06]]), Brazil (in [[Big Brother Brasil 6|2006]] and [[Big Brother Brasil 15|2015]]), Bulgaria (in [[Big Brother 3 (Bulgarian season)|2006]], [[Big Brother All Stars 2012|2012]] and [[VIP Brother season 9|VIP 2017]]), United Kingdom (in [[Big Brother (British TV series) series 8|2007]], [[Celebrity Big Brother (British TV series) series 8|Celebrity 2011]], [[Celebrity Big Brother (British TV series) series 9|Celebrity 2012]], [[Big Brother (British TV series) series 14|2013]], [[Big Brother (British TV series) series 16|2015]], [[Big Brother (British TV series) series 17|2016]] and [[Celebrity Big Brother (British TV series) series 19|Celebrity 2017]]), France (in [[Secret Story (French TV series) season 1|2007]], [[Secret Story (French TV series) season 5|2011]], [[Secret Story (French TV series) season 7|2013]], [[Secret Story (French TV series) season 9|2015]] and [[Secret Story (French TV series) season 10|2016]]), Spain (in [[Gran Hermano (Spanish TV series) season 9|2007]] and [[Gran Hermano (Spanish TV series) season 14|2013]]), Poland (in [[Big Brother (Polish TV series) season 4|2007]] and [[Big Brother (Polish TV series) season 7|2019]]), India (in [[Bigg Boss (Hindi TV series) season 2|2008]]), Africa (in [[Big Brother Africa season 4|2009]]), Balkan Region (in [[Big Brother (Serbian TV series) season 3|2009]] and [[Big Brother VIP (Serbian TV series) season 5|2013]]), Philippines (in [[Pinoy Big Brother: Double Up|2009]], [[Pinoy Big Brother: Teen Edition 4|Teen 2012]] and [[Pinoy Big Brother: All In|2014]]), Portugal (in [[Secret Story 1 (Portuguese season)|2010]] and [[Secret Story 3 (Portuguese season)|2012]]), Israel (in [[Big Brother (Israeli TV series) season 3|2011]]), Ukraine (in [[Big Brother (Ukrainian TV series)|2011]]), Argentina (in [[Gran Hermano (Argentine TV series) season 7|2011]] and [[Gran Hermano (Argentine TV series) season 9|2016]]), Albania (in [[Big Brother (Albanian TV series) season 6|2013]], [[Big Brother (Albanian TV series) season 9|2017]], [[Big Brother VIP (Albanian TV series) season 1|Celebrity 2021–22]] and [[Big Brother VIP (Albanian TV series) season 2|Celebrity 2022–23]]), Greece (in [[Big Brother (Greek TV series) season 6|2020]]) and Kosovo (in [[Big Brother VIP Kosova|Celebrity 2022–23]]).

==== Pairs competitions ====
Several versions of the program feature variations of the housemates competing in pairs:

* In the [[Big Brother 6 (American season)|sixth American season]], each HouseGuest had a secret partner with whom had a pre-existing relationship, with each pair being informed that they were the only secret pair. While each player was nominated and evicted as an individual, each pair had the goal of reaching being the Final 2 HouseGuests remaining. Should a secret pair succeed in this goal, the prize money awarded to the winner and runner-up would jackpot – the winner's prize doubling from $500,000 to $1,000,000 and the runner-up's prize quintupling from $50,000 to $250,000. 
* During the tenth week of the [[Big Brother (British TV series) series 7|seventh British series]], the housemates were paired with their "best friend" in the house and had to nominate and face eviction as couples. 
** The [[Big Brother 9 (American season)|ninth American season]] added a romantic theme by pairing up the HouseGuests with their "Soulmate" and having them compete as couples. This twist was active for the first 3 weeks of the season. 
** The [[Big Brother 13 (American season)|13th American season]] featured a further twist to the pairs format by introducing the "Dynamic Duos" twist, where contestants formed pairs that would be nominated together but evicted separately. The nominee not evicted would be immune from further nomination until there were 10 HouseGuests remaining, at which point the pairs were dissolved. This twist was repeated in [[Big Brother 24 (American season)|24th American season]], except with the surviving partner joining another pair to compete alongside. 
* The second season of the [[Pinoy Big Brother: Teen Edition Plus|Philippine teen edition]] also featured the parents or guardians of the teens staying in the house; if a teen housemate was evicted, the coinciding parent or guardian would also be evicted. A similar twist was used on the [[Big Brother (Greek TV series)|fourth Greek season]] was dubbed ''[[Big Brother (Greek TV series) season 4|Big Mother]]''; it featured housemates accompanied by their mothers.
* In the ninth season of [[Bigg Boss (Hindi TV series)|Indian ''Big Brother'']], ''[[Bigg Boss (Hindi TV series) season 9|Big Boss: Double Trouble]]'', contestants entered the house tied up in pairs by the waist. They had joint chairs, beds, spoons, and even mugs. The twelfth season of [[Bigg Boss|Indian ''Big Brother'']], ''[[Bigg Boss (Hindi TV series) season 12|Bigg Boss 12]]'' also featured jodis (pairs) who were Teacher-Student, Policeman-Lawyer, sister-sister, etc.
* In the [[Big Brother 9 (Albania)|ninth Albania season]], all the housemates wherever were in couples and for the first time in the history of ''Big Brother Albania'', the winner was a couple (Danjel Dedndreaj and Fotini Derxho).

==== Secret missions ====

Secret missions are a common element of the show since their introduction during the [[Big Brother (British TV series) series 6|sixth British series]]. During these missions, one or more housemates are set a task from ''Big Brother'' with the reward of luxuries for the household and/or a personal reward if the task is successful. Some versions of ''Big Brother'' have secret tasks presented by another character who lives in plain sight of the housemate. Such characters include Marsha the Moose (from ''BB Canada'') and Surly the Fish (from ''BB Australia'').

The [[Big Brother (Belgian TV series)|third Belgian season]] introduced a mole. This housemate was given secret missions by ''Big Brother''.<ref>[https://www.demorgen.be/nieuws/de-mol-infiltreert-in-big-brother~b17a0cf0/ 'De Mol' infiltreert in 'Big Brother'], De Morgen, 2 September 2002</ref>

The sixth Australian season featured The Insider. Voted on by Australia, the Housemates deemed "The Most Competitive" had to complete secret missions tasked by Big Brother in order to win immunity from Nomination Voting and hence, Eviction. Failure in a mission would result in Automatic Nomination. 

The [[Big Brother 8 (American season)|eighth American season]] introduced "America's Player", where a selected house guest must complete various tasks (determined by public vote) in secret for the duration of their stay in the house in exchange for a cash reward. It was repeated in the [[Big Brother 10 (American season)|tenth American season]] for a week. The [[Big Brother 11 (American season)|eleventh American season]] featured Pandora's Box, in which the winning head of household was tempted to open a box, with [[unintended consequences]] for the house. The [[Big Brother 12 (American season)|twelfth American season]] featured a saboteur, who entered the house to wreak havoc with tasks suggested by viewers. The [[Big Brother 16 (American season)|sixteenth American season]] featured "Team America", in which 3 houseguests were selected to work as a team to complete tasks (determined by public voting) for a cash reward; this continued for the entire season despite the eviction of a team member.

The [[Gran Hermano Argentina#Season 4|fourth Argentine series]] added a telephone in the living room. This telephone rang once a week for ten seconds, and the person to pick up the receiver was given an order or news from Big Brother (which typically no other housemate could hear). The order could be beneficial or detrimental, but a refused order resulted in the nomination for eviction. If nobody picked up the call, the whole house would be nominated for eviction.{{citation needed|date=October 2017}}<!-- WP:RS needed; removed link to WP-->

==== Opening night twists ====
Since ''[[Big Brother (British TV series) series 2|Big Brother 2]]'', the [[Big Brother (British TV series)|British series]] has opened with a twist. This has included having potential Housemates being voted upon by the public for one to enter the house (''Big Brother 2'' & [[Big Brother (British TV series) series 13|''Big Brother 13'']]); public voting for least-favourite housemates, with the housemates choosing between two nominees to evict (''Big Brother 3''); first-night nominations (''[[Big Brother (British TV series) series 4|Big Brother 4]]'' & [[Big Brother (British TV series) series 13|''Big Brother 13'']]); suitcase nominations (''Big Brother 5''); Unlucky Housemate 13 (''Big Brother 6''); Big Brother Hood (''[[Big Brother (British TV series) series 7|Big Brother 7]]''); an all-female house and a set of twins as contestants (''[[Big Brother (British TV series) series 8|Big Brother 8]]''); a couple entering as housemates, who must hide their relationship (''[[Big Brother (British TV series) series 9|Big Brother 9]]''); housemates having to earn housemate status (''[[Big Brother (British TV series) series 10|Big Brother 10]]'', with an altered version of the twist appearing in ''[[Big Brother (British TV series) series 21|Big Brother 21]]''); a [[Mole (espionage)|mole]] entering the house with an impossible task (''[[Big Brother (British TV series) series 11|Big Brother 11]]''); [[Pamela Anderson]] entering as a guest for 5 days (''[[Big Brother (British TV series) series 12|Big Brother 12]]''); a professional actor posing as a housemate and a mother and daughter as contestants (''[[Big Brother (British TV series) series 14|Big Brother 14]]''); one contestant gets a pass to the final (''[[Big Brother (British TV series) series 15|Big Brother 15]]''); first night eviction (''[[Big Brother (British TV series) series 16|Big Brother 16]]''); two houses with "the other house" featuring enemies from the main house housemates past (''[[Big Brother (British TV series) series 17|Big Brother 17]]''); [[Jackie Stallone]] entering a house containing her son's ex-wife [[Brigitte Nielsen]] (''[[Celebrity Big Brother (British TV series) series 3|Celebrity Big Brother 3]]''); a "fake celebrity" (a civilian contestant pretending to be a celebrity) in a celebrity edition (''[[Celebrity Big Brother (British TV series) series 4|Celebrity Big Brother 4]]''); a visit from [[Jade Goody]]'s family (''[[Celebrity Big Brother (British TV series) series 5|Celebrity Big Brother 5]]'') and unlocked bedrooms allowing housemates to immediately claim beds<ref>{{cite news | url=https://www.mirror.co.uk/celebs/news/2009/01/05/celebrity-big-brother-exclusive-la-toya-jackson-s-diva-demands-115875-21016252/ | title=Celebrity Big Brother exclusive: La Toya Jackson's diva demands – 3am & Mirror Online | newspaper=[[Daily Mirror]] | date=25 January 2009 | access-date=15 July 2013 | author=Bryant, Tom}}</ref> with the last housemate becoming the Head of House (''[[Celebrity Big Brother (British TV series) series 6|Celebrity Big Brother 6]]'').

A common opening twist is to introduce only a cast of a single sex on the premiere of the show while having members of the opposite sex introduced over the next few days. The [[Big Brother (British TV series) series 8|eighth British series]] first used this twist with an initial all-female house, adding a male housemate two days later. The same twist was used in the [[Big Brother 4 (Bulgarian season)|fourth Bulgarian series]], and an all-male premiere was used on ''[[Big Brother Africa season 4|Big Brother Africa 4]]''. The [[Big Brother (Belgian TV series) season 2|second Belgian season]] was used a similar twist in 2001, where eleven male housemates and one female housemate entered the house on launch night and the second female housemate entered the house on the third day.

==== Fake evictions ====

The [[Big Brother (British TV series) series 5|fifth British series]] introduced fake evictions, where Big Brother misleads housemates that eviction has taken place, only for the "evicted" housemate to reenter the house sometime later.

In the [[Big Brother (British TV series) series 8|eighth British series]], one housemate was evicted, interviewed and sent back into the house.

In the [[Pinoy Big Brother: All In|fifth Philippine season]], four housemates were fake-evicted and stayed in a place called ''bodega''. In the second batch of the [[Pinoy Big Brother: Otso|eight Philippine season]], four housemates were fake-evicted due to losing their duel challenge and temporarily stayed in a secret room. In the adult edition of the [[Pinoy Big Brother: Kumunity Season 10|tenth Philippine season]], two housemates, and later three more, were fake evicted after failing in two different ''Ligtask'' challenges and temporarily stayed in the task room until the end of their weekly task.

The concept of the fake-eviction was incorporated into the Australian series for the first time in the [[Big Brother (Australian TV series) season 6|sixth Australian season]], when housemates Camilla Severi and Anna Lind-Hansen were both fake-evicted in Day 8 and were moved into a secret room in the house, the Revenge Room. Severi and Lind-Hansen could see who nominated them for eviction and were given the opportunity to wreak havoc upon the house and those who nominated them by constructing extravagant tasks for the housemates to complete and for making mess in the house when they were not looking. Severi and Lind-Hansen returned to the house in a live special on Day 10. In the [[Big Brother (Australian TV series) season 10|tenth Australian season]], Benjamin Zabel was fake evicted for 24 hours before being returned to the house with immunity from eviction for that week. In the [[Big Brother (Australian TV series) season 11|eleventh Australian season]] Travis Lunardi was fake-evicted and received advice from Benjamin Zabel for 24 hours; Travis returned to the house after a 3-day absence with immunity from eviction for that week.

In the [[Big Brother Brasil 13|thirteenth Brazilian series]], Anamara Barreira was fake evicted. She was removed and put into a small private apartment without the other housemates knowing she was still in the house. After 24 hours, she returned to the house as Head of Household and with immunity from eviction that week. In the [[Big Brother Brasil 16|sixteenth Brazilian series]], Ana Paula Renault was similarly fake evicted, put into a small private apartment, and returned after 48 hours with immunity from eviction that week. In the [[Big Brother Brasil 18|eighteen Brazilian series]], Gleici Damasceno was similarly fake evicted, put into a small private apartment, and returned after 72 hours with immunity from eviction and with the power to put someone to eviction.

In the [[Big Brother Türkiye|first Turkish series]], there is a fake eviction in week 10.

The Indian version ''[[Bigg Boss (franchise)|Bigg Boss]]'' sees frequent fake evictions. In ''[[Bigg Boss Kannada]]'' [[Bigg Boss Kannada season 4|season 4]], winner Pratham and co-contestant Malavika were kept in secret room after fake eviction for one week and they were both allowed in the Bigg Boss house.

Similarly, in ''[[Bigg Boss Kannada]]'' [[Bigg Boss Kannada season 5|season 5]], firstly Jaya Srinivasan and Sameer Acharya were put into the secret room after fake eviction for one week and then Sameer Acharya was allowed into the house, but Jaya Srinivasan was evicted from the secret room itself. In the same season, the runner up Divakar was put into the secret room after fake eviction for one week.

==== Coaches ====
[[Big Brother 14 (American season)|The fourteenth American season]] had four house guests from past seasons return to coach twelve new house guests, playing for a separate prize of $100,000. However, in a reset twist, they opted to join the normal game alongside the other house guests.

==== Red button ====
The seventh Argentine series incorporated a red button into the Confession Room, which would sound an alarm throughout the house. This button was to be used when a contestant wanted to leave the house voluntarily, and the contestant would be given five minutes to leave the house. A red button is also used in ''[[Secret Story (France)|Secret Story]]'' series, however, in this case whoever presses the button will try to guess someone's secret.

==== Legacy rewards or penalties ====
In ''[[Big Brother: Celebrity Hijack|Celebrity Hijack UK]]'', evicted housemates were given the opportunity to choose if a "ninja" delivered good or bad gifts to the house. Later that year, the [[Big Brother (Australian TV series) season 8|eighth Australian series]] introduced the Housemate Hand Grenade, where an evicted housemate decided which remaining housemate received a penalty. A similar punishment used on ''[[Big Brother Africa]]'' was called the Molotov Cocktail, Dagger or Fuse.

==== Most valuable player ====
The [[Big Brother 15 (American season)|fifteenth American season]] allowed viewers to vote for a house guest to be made M.V.P., who then secretly nominates a third houseguest for eviction (in addition to the two selected by the Head of Household).

In a further twist introduced part-way through the MVP twist, the viewers themselves decided who the third nominee would be, with the HouseGuests still thinking one of their own is the MVP. Like many such twists, this was ended halfway into the season as the pool of contestants shrank.

==== Multiple heads of household ====
The [[Big Brother 16 (American season)|sixteenth]] and [[Big Brother 17 (American season)|seventeenth]] American seasons featured two Heads of Household every week and had four houseguests nominated for eviction. There was also a "Battle of the Block" competition where the two sets of nominees competed to save themselves; the winning pair not only saved themselves but dethroned the Head of Household who nominated them, who was then vulnerable as a replacement nominee if a veto was used. It is also used in specific weeks in Brazil since ''[[Big Brother Brasil 16]]'' where the HOH's have to choose which HoH will get [[Brazilian real|R$]]10,000 and who is the one that will win immunity.

==== America's Favorite HouseGuest ====
In the American version, each season there are three cash prizes: $750,000 for the winner, $75,000 for second, and $50,000 for who was voted by the viewers to be America's Favorite HouseGuest.

==== Multiple winners ====
In 2011, ''[[Big Brother Africa]]'' [[Big Brother Africa season 6|season 6]] was the first season of ''Big Brother'' to have two winners, each getting US$200,000.

In 2012, the four finalists from ''[[Gran Hermano (Spanish TV series) season 13|Gran Hermano 12+1]]'' (Spain) were given the chance to choose a formerly evicted housemate to be their partner. The companion of the winner became the "+1 winner" and received a secondary prize of €20,000.

In 2015, the [[Pinoy Big Brother: 737|sixth Philippine season]], also had two winners; one from the [[Pinoy Big Brother: 737 – Part 1|teens]] and one from the [[Pinoy Big Brother: 737 – Part 2|regular adults]]. Each of which received PHP1,000,000.

''[[Bigg Boss (Hindi TV series) season 8|Bigg Boss 8]]'' (India) ended with a twist, where the top five contestants were crowned 'champions'. The season was extended by 35 days (total 135) as a spin-off called ''[[Bigg Boss Halla Bol]]'', where ex-contestants from previous seasons entered the house to compete with the five champions.

==== Reserve housemates ====
The [[Pinoy Big Brother: Unlimited|fourth Philippine season]] introduced the concept of having reserved housemates, those of whom are short-listed auditioners who were given a chance to be a housemate by completing tasks assigned by Big Brother. It was eventually done also in the [[Pinoy Big Brother: Otso|eighth Philippine season]] where the reserved housemates were placed in a camp (a separate House but is just adjacent to the Main House) and that reserved housemate must compete amongst other reserved housemates while gaining points by participating in various tasks, including those that required the participation of doing such tasks outside of the Big Brother House premises. As the eviction was done weekly, once an official housemate is evicted from the Main House, the {{Not a typo|housemate(s)}} with the most points earned for that particular week crossovers to the Main House and becomes an official housemate.

These reserved housemates twist was also used in Argentina's [[Gran Hermano Argentina (season 7)|seventh season]] and Brazil's [[Big Brother Brasil 9|ninth season]].

==== ''Big Brother Zoom'' ====

In 2020, due to the [[COVID-19 pandemic]], the ''[[Big Brother (Portuguese TV series) season 5|Big Brother Portugal]]'' revival started with a twist, where all the contestants were isolated in different apartments for 14 days, in line with World Health Organisation (WHO) recommendations. Cameras were filming them 24 hours a day as usual, and they were able to communicate with each other and host Cláudio Ramos using tablets.<ref>{{cite news | url=http://www.bbspy.co.uk/bb19/news/0421/big-brother-portugal-to-launch-with-the-circle-style-coronavirus-twist#ixzz6KHsYm4Nq | title=Big Brother Portugal to launch with The Circle-style coronavirus twist | date=21 April 2020 | access-date=21 April 2020 | archive-date=8 June 2020 | archive-url=https://web.archive.org/web/20200608071509/http://www.bbspy.co.uk/bb19/news/0421/big-brother-portugal-to-launch-with-the-circle-style-coronavirus-twist#ixzz6KHsYm4Nq | url-status=dead }}</ref>

In 2005, United Kingdom (Nadia Almada of [[Big Brother (British TV series) series 5|BB5]]) visited Australia ([[Big Brother (Australian TV series) season 5|BB5]]) again. In 2006, United Kingdom ([[Chantelle Houghton]] of [[Celebrity Big Brother (British TV series) series 4|CBB4]]) visited Germany ([[Big Brother (German TV series) season 6|BBG6]]).

=== ''Celebrity'' and ''VIP'' ''Big Brother'' ===
{{Main|Celebrity Big Brother}}

The ''Big Brother'' format has been adopted in some countries; the housemates are local celebrities, and the shows are called ''[[Celebrity Big Brother]]'' or ''[[Celebrity Big Brother|Big Brother VIP]]''. In some countries, the prize money normally awarded to the winning housemate is donated to a charity, and all celebrities are paid to appear in the show as long as they do not voluntarily leave before their eviction or the end of the series. The rest of the rules are nearly the same as those of the original version.

==== Variations ====
The 2006 Netherlands series was entitled ''Hotel Big Brother''. This variation introduced a group of celebrity hoteliers and a Big Boss, who run a hotel and collect money for charity without nominations, evictions or a winner.

Another variation appeared in the UK in early 2008, entitled ''[[Big Brother: Celebrity Hijack]]''. Instead of being housemates the celebrities became Big Brother himself, creating tasks and holding nominations with the help of Big Brother. The housemates were considered by the producers "Britain's most exceptional and extraordinary" 18- to 21-year-olds. The prize for the winner of the series was £50,000.<ref name="celebhijack">{{cite web|url=http://www.channel4.com/entertainment/tv/microsites/B/bb8/news/newsstory.jsp?id=24561|title=BB Celebrity Hijack |publisher=[[Channel 4]]|url-status=live|archive-url=https://web.archive.org/web/20070621073443/http://www.channel4.com/entertainment/tv/microsites/B/bb8/news/newsstory.jsp?id=24561|archive-date=21 June 2007|access-date=24 May 2014}}</ref>

In 2009, ''[[VIP Brother 3]] Bulgaria'' introduced the concept of celebrities competing for charitable causes, which changed each week. Housemates were sometimes allowed to leave the house to raise money for the charity. Ten out of Thirteen seasons of ''[[Bigg Boss]]'' (the Indian version of ''Big Brother'') have been celebrity-only seasons. The 10th season of ''Big Boss'' had celebrities put up against commoners, where a commoner ultimately won.

=== American format ===
{{Further|topic=these Big Brother versions|Big Brother (American TV series)|Big Brother Canada}} 
The American and Canadian versions of ''Big Brother'' differ from most global versions of the series. The American series began in 2000 with the original Dutch format—i.e., housemates, or HouseGuests, as they are styled in the United States, nominating each other for eviction and the public voting on evictions and the eventual winner. But due to both poor ratings and the concurrent popularity of ''[[Survivor (American TV series)|Survivor]]'', a gameplay-oriented format was introduced in the [[Survivor (American TV series)|second season]], with HouseGuests allowed to strategize, politic and collude to survive eviction, with the entire nomination and eviction process being determined by the HouseGuest themselves.

Each week the HouseGuests compete in several competitions in order to win power and safety inside the house, before voting off one of the HouseGuests during the eviction. The main elements of the format are as follows:
*'''Head of Household (HoH):''' At the start of each week in the house, the HouseGuests compete for the title of Head of Household, often shortened to simply HoH.<ref name="format-ep1">{{cite episode |title=Episode One |series=Big Brother 12 |series-link=Big Brother (U.S.) |network=CBS |airdate=8 July 2010 |minutes=00:25 |season=12 |number=1}}</ref> The Head of Household for each week is given luxuries such as their own personal bedroom and the use of an [[MP3 player]] but is responsible for nominating two of their fellow HouseGuests for eviction. The Head of Household would not be able to compete in the following week's Head of Household competition; this excludes the final Head of Household competition of the season.<ref name="Pickard">{{cite news |last=Pickard |first=Ann |title=Why is Big Brother so big in the US? |work=The Guardian |date=19 August 2009 |url=https://www.theguardian.com/media/organgrinder/2009/aug/19/why-big-brother-big-us |access-date=25 May 2010 |location=London}}</ref><ref name="format-ep2">{{cite episode |title=Episode Two |series=Big Brother 11 |series-link=Big Brother (U.S.) |network=CBS |airdate=12 July 2009 |minutes=35:57 |season=11 |number=1}}</ref><ref name="format-ep3">{{cite episode |title=Episode Three |series=Big Brother 11 |series-link=Big Brother (U.S.) |network=CBS |airdate=14 July 2009 |minutes=39:20 |season=11 |number=1}}</ref>
*'''Power of Veto (PoV):''' After the nominees are determined, the Power of Veto competition is played, with the winner receiving the Power of Veto. If a HouseGuest chooses to exercise the Power of Veto, the Head of Household is responsible for naming a replacement nominee.<ref name=veto>{{Cite web|url=http://www.bbspy.co.uk/bbcan/features/0306/how-big-brother-usa-canada-format-works-explained-ultimate-guide|title=Big Brother USA and Canada format: The ultimate guide|website=bbspy|date=6 March 2020|access-date=8 February 2021|archive-date=8 February 2021|archive-url=https://web.archive.org/web/20210208174649/http://www.bbspy.co.uk/bbcan/features/0306/how-big-brother-usa-canada-format-works-explained-ultimate-guide|url-status=dead}}</ref> The holder of the Power of Veto is saved from being nominated as the replacement nominee.<ref>{{Cite news|url=https://www.tvguide.com/news/big-brother-dumbest-moves-ever/|title=_Big Brother_: The 11 Dumbest Moves Ever|website=TVGuide.com}}</ref> Only six of the HouseGuests compete for the Power of Veto each week; the Head of Household and both nominations compete, as well as three others selected by a random draw. The PoV was introduced in the third American season
*'''Eviction:''' On eviction night, all HouseGuests must vote to evict one of the nominees, with the exception of the nominees and the Head of Household. The eviction vote is by [[secret ballot]], with HouseGuests casting their votes orally in the Diary Room. In the event of a tied vote, the Head of Household will cast a tie-breaking vote publicly. The nominee with the majority of the votes is evicted from the house.<ref name="format-ep4">{{cite episode |title=Episode Four |series=Big Brother 11 |series-link=Big Brother (U.S.) |network=CBS |airdate=16 July 2009 |minutes=33:20 |season=11 |number=1}}</ref>

Before the [[Big Brother 16 (American season)|sixteenth American season]], HouseGuests competed in a Have/Have-Not challenge similar to the shopping tasks on ''Big Brother UK'' and other international editions. The winners become Haves and enjoy a full pantry of food, while Have-Nots, will be left with a staple diet of "slop" (fortified oatmeal), sleep in designated uncomfortable beds and take cold showers. In later seasons, the Haves & Have-Nots are determined either by the HoH themself or by the results of the HoH Competition.

When only two contestants remain, a jury formed of the most recently evicted HouseGuests (generally seven or nine) votes which of the two finalists wins the grand prize. Beginning in the fourth (2003) American season, jury members were sequestered off-site so that they would not be privy to the day-to-day goings-on in the house. (''Celebrity Big Brother US'' does not sequester its jury members—all evicted celebrity HouseGuests vote on the winner.).<ref>{{cite web |last=Powell |first=John |title='Big Brother' twist unveiled |work=JAM! Showbiz |date=23 August 2003 |url=http://jam.canoe.ca/Television/TV_Shows/B/BigBrother4/2004/12/14/782371.html |archive-url=https://archive.today/20120710222604/http://jam.canoe.ca/Television/TV_Shows/B/BigBrother4/2004/12/14/782371.html |url-status=usurped |archive-date=10 July 2012 |access-date=25 May 2010}}</ref> The final Head of Household competition is split into three parts; the winners of the first two rounds compete in the third and final round. Once only two HouseGuests remain, the members of the jury cast their votes for who should win the series.<ref>{{cite web|url=http://detroit.cbslocal.com/2012/09/20/big-brother-14-finale-episode-breakdown-ian-quacks-to-500k/|title='Big Brother' 14 Finale Episode Breakdown: Ian Quacks To 500K « CBS Detroit|date=20 September 2012|access-date=28 October 2014}}</ref>

In addition, American and Canadian ''Big Brother'' do not air a live launch show, as is customary in international editions—by the time the network show and live online feeds begin airing, it is not uncommon for at least one HouseGuest to already have been evicted. Also, the North American editions currently air only three times a week, compared with daily or six days a week for the recently rebooted British franchise. As a result, the TV episodes focus primarily on the main events regarding the gameplay and house politics versus the day-to-day goings-on in the house; to see the latter, watching the live feeds is necessary.

In 2013, English-speaking Canada introduced its own version of the show on the cable channel [[Slice (TV channel)|Slice]]; the series moved to [[Global TV]] for its third (2015) season. The show followed the American format but with more elaborate twists and greater viewer participation in the game. Secret tasks were introduced, usually presented by the show's mascot, "Marsha the Moose"; also, as in most global franchises, Big Brother was a distinct character who interacted with the HouseGuests. The [[Big Brother (Quebec TV series)|French Canadian version]] mostly followed the American/Anglophone Canadian format, but the public could evict a housemate on some occasions and decided the winner.

The [[Big Brother (Australian TV series) season 12|2020 revival]] of the ''[[Big Brother (Australian TV series)|Big Brother Australia]]'' series adopted a slightly altered version of the American format (having previously used the international format) while pre-recording the series months in advance. A "Nomination Challenge" is held to determine who holds the power to nominate for that round, with the winner naming three Nominations for Eviction. During each eviction, all Housemates (excluding the Nominating Housemate) vote to evict. There is no rule prohibiting individuals holding Nomination Power in consecutively between weeks and no Power of Veto is held. Additionally, the Australian public still decided the winner between the final 3.

''[[Big Brother Brasil]]'' combines the American/Canadian and international formats. Brazil votes on evictions and the winner, but housemates compete for HoH, Power of Immunity, and Power of Veto; there is also a weekly shopping competition. HoH nominates one housemate for eviction, while the rest of the house nominates a second housemate. The winner of the Power of Immunity competition gets to choose someone to be safe from nomination.

The pilot for ''[[Big Brother China]]'', which premiered exclusively online in 2015, had housemates voting on evictions but the public voting for the winner.<ref>{{cite web|url=http://www.bbspy.co.uk/cbb16/news/1121/big-brother-china-pilot-season-premieres-online-youku-tudou-housemates-lets-stay-together-india-house-bigg-boss|title=Big Brother China launches with twelve-day 'pilot series'|last=bbspy|date=21 November 2015|access-date=3 July 2017|archive-date=31 December 2017|archive-url=https://web.archive.org/web/20171231155355/http://www.bbspy.co.uk/cbb16/news/1121/big-brother-china-pilot-season-premieres-online-youku-tudou-housemates-lets-stay-together-india-house-bigg-boss|url-status=dead}}</ref> A similar format was used for ''[[Big Brother: Over the Top]]'', an online-only spin-off of the American series that ran in 2016.

The [[Big Brother (British TV series) series 19|nineteenth series]] of ''[[Big Brother (British TV series)|Big Brother UK]]'' saw the adaption of the "Game Changer" competition which is very similar to the Power of Veto competition. The winner of this competition has the opportunity to save a nominee from eviction. Like the PoV, there are six people that play in the "Game Changer" competition. The process of how the contestants are chosen is different as the people who have been nominated play in the competition along with the richest housemate. If there are empty left in the competition, then the richest housemate hand picks who will playing in that weeks "Game Changer" competition. The winner of the competition, like the PoV, has the option to save housemate from eviction for the week or not use the power at all. Unlike the PoV however, if the winner does save someone then no replacement nominee was named leaving the remaining nominees up for eviction and facing the public vote.<ref>{{Cite web|title=Big Brother have announced a new twist and it is a total game changer|url=https://www.her.ie/entertainment/big-brother-announced-new-twist-game-changer-426480|access-date=24 November 2020|website=Her.ie|date=22 September 2018 |language=en}}</ref><ref>{{Cite web|last=Darvill|first=Josh|date=26 September 2018|title=Big Brother 2018 spoilers as housemates take part in the 'Game changer'|url=https://tellymix.co.uk/gallery/375643-pictures-big-brother-2018-spoilers-as-housemates-take-part-in-the-game-changer.html|access-date=24 November 2020|website=TellyMix|language=en|archive-date=27 September 2020|archive-url=https://web.archive.org/web/20200927210136/https://tellymix.co.uk/gallery/375643-pictures-big-brother-2018-spoilers-as-housemates-take-part-in-the-game-changer.html|url-status=dead}}</ref><ref>{{Cite web|last=Darvill|first=Josh|date=24 October 2018|title=Big Brother spoilers as housemates take on the final game changer task|url=https://tellymix.co.uk/gallery/380326-big-brother-2018-spoilers-as-housemates-take-on-the-final-game-changer-task.html|access-date=24 November 2020|website=TellyMix|language=en|archive-date=24 September 2020|archive-url=https://web.archive.org/web/20200924023907/https://tellymix.co.uk/gallery/380326-big-brother-2018-spoilers-as-housemates-take-on-the-final-game-changer-task.html|url-status=dead}}</ref>

There are also "test runs", with a group of celebrities (or journalists) living in the house for several days to test it. There are occasions where people who have auditioned for the show are also put in the house, most notably in the British edition, where many housemates claim to have met before. These series have been televised in [[Argentina]], Bulgaria, [[Czech Republic]], Germany, Mexico, the Pacific region, the Philippines and Spain. In some cases, it is not broadcast, but in others, such as the American edition, it is used as a promotional tool.

== Controversies ==

=== Legal ===
In April 2000, Castaway, an independent production company, filed a lawsuit against John de Mol and Endemol for stealing the concepts of their own show called ''[[Survivor (American TV series)|Survive!]]'', a reality television show where contestants are placed on a deserted island and have to take care of themselves alone. These contestants were also filmed by cameras around them.<ref>{{cite news | url=https://news.bbc.co.uk/2/hi/entertainment/720966.stm | title=Geldof's Big Brother battle | publisher=[[BBC News]] | date=20 April 2000 | access-date=23 May 2014}}</ref> The court later dismissed the lawsuit filed by Castaway against de Mol and Endemol. The ''Survive!'' reality television format was later turned into ''[[Survivor (American TV series)|Survivor]]''.<ref>{{cite news | url=https://news.bbc.co.uk/2/hi/entertainment/893180.stm | title=Blow for mogul's Big Brother claim | publisher=[[BBC News]] | date=24 August 2000 | access-date=23 May 2014}}</ref>

In 2000, the estate of George Orwell sued CBS Television and Endemol for copyright and trademark infringement, claiming that the program infringed on the Orwell novel ''1984'' and its trademarks. After a series of court rulings adverse to the defendants (CBS and Endemol), the case was settled for an undisclosed amount of money on the evening of the trial.<ref>Estate of George Orwell v.

=== Sexual assault ===
There have been three documented occurrences of possible rape happening during the show. In ''Big Brother South Africa'', a male housemate was accused of assaulting a fellow housemate while she was asleep. The pair were filmed kissing and cuddling in bed before the cameras moved away and the male housemate reportedly claimed to housemates the next day that he had intercourse with the contestant. However, the female housemate was apparently shocked by the claims and informed female housemates that she had not consented to have sex with him (under South African law, this act would be constituted as rape).<ref name=africarape>{{cite web|last1=Paterson|first1=Mark|title=Big Brother's South African rape horror show|url=http://www.theweek.co.uk/tv-radio/big-brother/28073/big-brother%E2%80%99s-south-african-rape-horror-show|website=The Week|publisher=Dennis Publishing|access-date=12 January 2015|archive-date=9 January 2015|archive-url=https://web.archive.org/web/20150109211636/http://www.theweek.co.uk/tv-radio/big-brother/28073/big-brother%E2%80%99s-south-african-rape-horror-show|url-status=dead}}</ref> This male housemate was expelled immediately after the allegations surfaced and was later arrested pending investigation, while the female housemate was removed from the house for her own protection and counselling. After this incident, the other housemates were warned not to attempt any further obscene actions, or they would be subject to a penalty of 43 years in prison and immediate expulsion from the house.

In ''Big Brother Brasil'', many viewers reported that they watched a male housemate allegedly force himself on a female housemate while she was passed-out drunk after a "boozy party". Soon after, the [[Federal Police of Brazil]] entered the house and arrested the offending housemate, who was later banned from ever appearing on the show again.<ref name=brazilrape>{{Cite web|url=https://www.theguardian.com/world/2012/jan/17/big-brother-brazil-alleged-rape|title=Big Brother Brazil contestant questioned over alleged rape|first=Tom|last=Phillips|date=17 January 2012|access-date=7 January 2020|work=The Guardian}}</ref>

Additionally, an incident of sexual assault occurred in the Australian Big Brother house in 2006, during the show's [[Big Brother (Australian season 6)|sixth season]]. Contestant Michael "John" Bric held down fellow contestant Camilla Severi in her bed while a second man, Michael "Ashley" Cox, "slapped" her in the face with his penis, an [[indecent]] act illegal under Australian law.<ref>{{Cite web|url=https://www.pedestrian.tv/entertainment/big-brother-turkey-slap/|title=How Big Brother's Infamous Turkey Slap Incident Changed Reality TV Forever|date=5 April 2018}}</ref> The incident was shown on the 'Adults-only' late-night segment, ''Big Brother: Adults Only'', leading to the show's cancellation. Both men involved in the incident were removed from the house.
