'''KSAZ-TV''' (channel 10) is a [[television station]] in [[Phoenix, Arizona]], United States. It is [[owned and operated]] by the [[Fox Broadcasting Company|Fox]] network through its [[Fox Television Stations]] division alongside [[KUTP]] (channel 45), which airs [[MyNetworkTV]] programming. The two stations share studios on West Adams Street in [[Downtown Phoenix]]; KSAZ-TV's transmitter is located atop [[South Mountains (Arizona)|South Mountain]].

Channel 10 was the third television station established in the Phoenix area, making its first broadcast on October 24, 1953. It was originally allocated as a shared-time channel to stations run by the owners of Phoenix radio stations [[KKNT|KOOL]] and [[KFYI|KOY]], though both KOOL-TV and KOY-TV operated from the same building. After a year as an [[independent station|independent]], it became Phoenix's original [[American Broadcasting Company|ABC]] affiliate in early 1954. KOOL-TV bought out KOY-TV later in 1954 and absorbed its staff, becoming a full-time station. After switching affiliations to [[CBS]] in 1955, KOOL-TV rose to become Phoenix's highest-rated station under the ownership of [[Gene Autry]] and Tom Chauncey. A falling-out between Autry and Chauncey ended with the sale of KOOL-TV to the Gulf United Corporation in 1982; separated from its sister radio properties, channel 10 changed its call sign to KTSP-TV. Initially, the station remained the news leader in Phoenix; however, in the late 1980s and early 1990s, the station lost ground in the news ratings to an ascendant [[KTVK]], which had poached two key KTSP-TV executives as part of a successful effort to turn itself around. Channel 10's ratings decline was not helped by several visible personnel miscues.

In February 1994, KTSP-TV changed its call letters to KSAZ-TV. Three months later, as part of the first act in a [[1994–1996 United States broadcast television realignment|national realignment of network affiliations]] initiated by then-owner New World Communications, the station announced it would switch from CBS to Fox. Phoenix was one of the most affected markets; the timing of affiliation contract expirations led to three changes in four months. KSAZ lost CBS in September 1994 but did not begin airing Fox programming until December. Coinciding with the switch to Fox was a major expansion of the station's news department, including new morning and prime time newscasts. However, the three months of forced independent status and miscalculations around syndicated programming and new competitors caused the station's ratings to fall dramatically, with some newscasts losing half their viewership.

Fox acquired the New World stations in 1996 and steadied the struggling operation, instituting a flashier style to bring it more in line with its target audience. From 1999 to 2021, future Arizona gubernatorial and senatorial candidate [[Kari Lake]] was one of the station's main anchors. By 2020, KSAZ-TV produced twelve hours a day on weekdays of local news programming.

==History==
===Shared-time era and early years===
While the [[Federal Communications Commission]] (FCC) worked its way toward ending a years-long freeze on new television station grants initiated in 1948, it issued a near-final version of the table of allocations for Arizona in 1951 that gave Phoenix channels 4 (changed to 3 the next year), 5 ([[KPHO-TV]], the only pre-freeze station in the state), 8, and 10. [[KKNT|KOOL (960 AM)]], Phoenix's [[CBS News Radio|CBS radio]] affiliate, had previously expressed interest in filing for channel 7 prior to the amended table being released,<ref name="Ariz510323">{{Cite news |date=March 23, 1951 |title=TV Channels Are Allocated For Arizona: New Assignments Made For Phoenix, Other State Cities |page=1 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/90600518/tv-channels-are-allocated-for-arizona/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 15, 2021 |archive-url=https://web.archive.org/web/20211215064815/https://www.newspapers.com/clip/90600518/tv-channels-are-allocated-for-arizona/ |url-status=live }}</ref><!-- Fri --> and on September 27, 1951, it applied for channel 10.<ref name="hc">{{Cite web|url=https://enterpriseefiling.fcc.gov/dataentry/api/download/attachment/410c803d-4153-fab0-00d8-84b0451051b5|title=History Cards for KSAZ-TV|publisher=[[Federal Communications Commission]]}}</ref>

KOOL was not alone in its interest. In July 1952, [[KFYI|KOY (550 AM)]], the home of the [[Mutual Broadcasting System]] in Phoenix and one of the oldest stations in the state, filed its own bid.<ref name="Ariz520725">{{Cite news |date=July 25, 1952 |title=KOY Seeks TV Channel 10 |page=22 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/90600677/koy-seeks-tv-channel-10/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 15, 2021 |archive-url=https://web.archive.org/web/20211215064811/https://www.newspapers.com/clip/90600677/koy-seeks-tv-channel-10/ |url-status=live }}</ref><!-- Fri --> The two bids portended what could have been years of comparative hearings over who got the construction permit. To avoid this, in May 1953, KOOL and KOY struck a deal that would result in both getting construction permits to share time on channel 10. The time-sharing proposal, first used by the FCC in television in grants for [[WHEC-TV|channel 10]] in [[Rochester, New York]], and suggested to KOOL and KOY by the commission,<ref name="Ariz530520">{{Cite news |last=Wilson |first=Maggie |date=May 20, 1953 |title=2 Stations Join Hands In TV Deal |page=7 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/90600738/2-stations-join-hands-in-tv-deal/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 15, 2021 |archive-url=https://web.archive.org/web/20211215064818/https://www.newspapers.com/clip/90600738/2-stations-join-hands-in-tv-deal/ |url-status=live }}</ref><!-- Wed --> was approved on May 27, 1953, with KOOL-TV and KOY-TV getting construction permits the same day.{{r|Ariz530528}} Under the proposal, the stations would alternate daytime and evening telecasting.{{r|Ariz530520}}

KOOL was the CBS radio affiliate in Phoenix, and KOOL expressed a desire to similarly align its new television station, but this would not be immediately possible. KPHO-TV, which held both CBS and ABC hookups after [[KTYL-TV]] signed on with NBC earlier in May, had just signed a renewal agreement with CBS a month and a half before the construction permits were granted.<ref name="Ariz530528">{{Cite news |date=May 28, 1953 |title=2 Stations Divide TV Channel 10 |page=2:1 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/90600821/2-stations-divide-tv-channel-10/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 15, 2021 |archive-url=https://web.archive.org/web/20211215064820/https://www.newspapers.com/clip/90600821/2-stations-divide-tv-channel-10/ |url-status=live }}</ref><!-- Thu --> Even though the two stations would have separate staffs and ownership, much of the physical plant would be shared, including a maximum-power transmitter site on South Mountain.<ref name="Ariz530610">{{Cite news |date=June 10, 1953 |title=TV Plans $500,000 To Outfit |page=19 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/90600979/tv-plans-500000-to-outfit/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 15, 2021 |archive-url=https://web.archive.org/web/20211215064814/https://www.newspapers.com/clip/90600979/tv-plans-500000-to-outfit/ |url-status=live }}</ref><!-- Wed --> Originally proposing to build television studios behind the KOY radio studios near First Avenue and Roosevelt Street,<ref name="Ariz530529">{{Cite news |date=May 29, 1953 |title=Third TV Unit Aims To Be On Air By Fall |page=16 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/90600885/third-tv-unit-aims-to-be-on-air-by-fall/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 15, 2021 |archive-url=https://web.archive.org/web/20211215064809/https://www.newspapers.com/clip/90600885/third-tv-unit-aims-to-be-on-air-by-fall/ |url-status=live }}</ref><!-- Fri --> KOOL and KOY arranged instead in July to buy a former car dealership at Fifth Avenue and Adams Street; KOY wanted to continue using the other site for parking.<ref name="Ariz530724">{{Cite news |last=Wilson |first=Maggie |date=July 24, 1953 |title=Tune In: New TV Channel 10 Plans Fall Opening |page=6 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/90601024/tune-in-new-tv-channel-10-plans-fall-op/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 18, 2021 |archive-url=https://web.archive.org/web/20211218044102/https://www.newspapers.com/clip/90601024/tune-in-new-tv-channel-10-plans-fall/ |url-status=live }}</ref><!-- Fri --> Studio construction started in August, with KOOL and KOY crews leading the way,<ref name="Ariz530815">{{Cite news |last=Wilson |first=Maggie |date=August 15, 1953 |title=Tune In: Channel 10 Begins Broadcast Oct. 1 |page=4 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/90601095/tune-in-channel-10-begins-broadcast-oct/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 18, 2021 |archive-url=https://web.archive.org/web/20211218044103/https://www.newspapers.com/clip/90601095/tune-in-channel-10-begins-broadcast/ |url-status=live }}</ref><!-- Sat --> and a test pattern went out for the first time on October 19, 1953,<ref name="Ariz531019">{{Cite news |date=October 19, 1953 |title=Channel 10 Telecasts Test Today |page=13 |work=Arizona Republic |location=Phoenix, Arizona |url=https://www.newspapers.com/clip/32885386/channel-10-telecasts-test-today/ |access-date=December 15, 2021 |via=Newspapers.com |archive-date=December 15, 2021 |archive-url=https://web.archive.org/web/20211215064813/https://www.newspapers.com/clip/32885386/channel-10-telecasts-test-today/ |url-status=live }}</ref><!-- Mon --> ahead of both stations' October 24 launch.

As a full-time CBS affiliate, it was now able to feature Autry's show ''Gene Autry's Melody Ranch'' on its schedule. Tom Chauncey, who also owned the biggest Arabian horse ranch in Phoenix, was a minority partner with Autry. Over the years, KOOL-TV ran nearly the entire CBS schedule; Chauncey was a fierce loyalist to the network.{{r|Ariz820929}} In addition to local news, channel 10 produced a series of other local programs, such as the bilingual children's program ''Niños Contentos'' and investigative and feature series ''Chapter 10'' and ''Copperstate Cavalcade''.{{r|Ariz820929}}

In 1964, Chauncey merged the KOOL radio and television news departments into a single division under the management of Bill Close, formerly of KOY radio.

Two of the hostages, Jack Webb and Bob Cimino, were released three hours later.
