IBM's subsequent [[Project Monterey]] was an attempt, circa 1999,  "to unify [[AIX]] with Sequent's Dynix/ptx operating system and [[UnixWare]]." By 2001, however, "the explosion in popularity of [[Linux]]  ... prompted IBM to quietly ditch" this.<ref>{{cite magazine  |magazine=Computerworld  |date=February 1, 1999 |page=28 |url=https://books.google.com/books?id=kxlABcUbI_wC
