the network's early years, unlike the owned-and-operated stations and affiliates of its established rivals. Those that did were mostly based in larger markets (including some of the network's O&Os) and retained newscasts that had aired for decades. Even then, these news operations were limited to one newscast per day, following the network's prime time lineup. On September 6, 1990, Fox reached an agreement with TCI (the nation's largest cable company at the time) in which TCI systems in markets that were not served by an over-the-air Fox affiliate at the time would become charter affiliates of a cable-only national feed of the network known as Foxnet. The cable-only network launched on June 6, 1991, bringing Fox programming to smaller markets that did not carry a default Fox affiliate at the time; it would manage to reach a total of 1.3 million subscribers by 1992. As Fox gradually headed towards carrying a full week's worth of programming in prime time through the addition of programming on Thursday and Friday nights at the start of the 1990–91 season the network's added offerings included the scheduling of The Simpsons opposite veteran NBC sitcom The Cosby Show as part of Fox's initial Thursday night lineup that fall (along with future hit Beverly Hills, 90210, which would become the network's longest-running drama, airing for ten seasons) after only a half-season of success on Sunday nights.

The sketch comedy series In Living Color, which debuted in April 1990, created many memorable characters and launched the careers of future movie stars Jim Carrey, Jamie Foxx, Damon Wayans, Marlon Wayans, Keenen Ivory Wayans, guest stars Chris Rock and Tim Meadows, and both members of the show's dance troupe, the "Fly Girls", Rosie Perez and Jennifer Lopez. The series also gained international prominence after Fox aired a special live episode in January 1992 as an alternative to the halftime show during Super Bowl XXVI, which was broadcast on CBS, marking the start of Fox's rivalry with the "Big Three" networks while popularizing the counterprogramming strategy against the Super Bowl telecast. The early and mid-1990s saw the debuts of several soap opera-style
