Although it was now part of a network, as was the case with other Fox stations during the network's early years, Channel 32, for all intents and purposes, continued to be programmed as a "de facto" independent station as Fox's initial programming consisted solely of a late-night talk show, "The Late Show Starring Joan Rivers"; even when Fox launched its prime time lineup in April 1987, the network only aired programs during that daypart on Saturday and Sundays early on; Fox would gradually debut additional nights of programming over the next six years until it adopted a seven-night-a-week schedule in September 1993. Until Fox began airing programming on a nightly basis, WFLD aired a movie at 7 p.m. (initially at 8 p.m. until 1988) on nights when network programs did not air. The afternoon and Saturday morning animation blocks were replaced by the network-supplied Fox Children's Network block (later known as Fox Kids) in September 1990. During the mid-1990s, WFLD continued to strengthen its programming schedule with acquisitions such as "The Simpsons", "Home Improvement" (which later moved to rival station WGN-TV in September 2001), and "Seinfeld" (which eventually moved to sister station WPWR, and later to WCIU-TV).
