respectively to WNYW and KDAF. These first six stations, then broadcasting to a combined reach of 22% of the nation's households, became known as the Fox Television Stations group. With the sole exception of KDAF (which was sold to Renaissance Broadcasting in 1995, at which time it became a charter affiliate of The WB), all of the original owned-and-operated stations ("O&Os") are still part of the Fox network today. Like the core O&O group, Fox's affiliate body initially consisted of independent stations (a few of which had maintained affiliations with ABC, NBC, CBS, or DuMont earlier in their existences). The local charter affiliate was, in most cases, that market's top-rated independent, however, Fox opted to affiliate with a second-tier independent station in markets where a more established independent declined the affiliation (such as Denver, Phoenix and St. Louis). Largely because of both these factors, Fox in a situation very similar to what DuMont had experienced four decades before had little choice but to affiliate with UHF stations in all except a few (mainly larger) markets where the network gained clearance. The Fox Broadcasting Company, or "FBC" as it was known back then, officially debuted with a soft launch at 11:00 p.m. Eastern and Pacific Time on Thursday, October 9, 1986. Its inaugural program was a late-night talk show, The Late Show, which was hosted by comedian Joan Rivers. After a strong start, The Late Show quickly eroded in the ratings; it was never able to overtake NBC stalwart The Tonight Show. By early 1987, Rivers (and her then-husband Edgar Rosenberg, the show's original executive producer) quit The Late Show after disagreements with the network over the show's creative direction, the program then began to be hosted by a succession of guest hosts. After that point, some stations that affiliated with FBC in the weeks before the April 1987 launch of its prime time lineup (such as WCGV-TV in Milwaukee and WDRB-TV in Louisville) signed affiliation agreements with the network on the condition that they would not have to carry The Late Show due to the program's weak ratings. Shortly before the official launch of FBC on April 5, 1987, under original Fox Entertainment President Garth Ancier, the network underwent a re-branding to the much shorter "Fox". According to an interview Ancier gave at that time, it was legendary ad man Jay Chiat who suggested to network executives that, rather than
