The 1980s and early 1990s
WPGH-TV, which had hitherto been a rather low-budget operation, was purchased by the Meredith Corporation in 1978, and became more aggressive with its programming strategy. Despite having a highly powerful signal that offered double the coverage of WPGH-TV's (5 million watts visual, compared to WPGH-TV's 2.345 million), WPTT-TV became unable to acquire newer shows, and ended up with programming that no other stations wanted. Still, the shows run on WPTT-TV were not exactly low-budget. The station's ratings were very low, and it was considered as an "also-ran" in the market. For many years, WPTT-TV languished as just another local independent station, airing reruns of television shows, many of which were past their prime. In 1986, Sinclair made an offer to buy WPGH-TV, combine programming assets onto Channel 22, keep channel 22, and sell weaker signaled Channel 53 to the Home Shopping Network, but were outbid by Lorimar-Telepictures. After that, WPTT-TV added some more recent shows, cartoons, and movies. By the late 1980s, both WPGH-TV, which was again sold, and WPTT-TV were losing money. WPTT-TV began running Home Shopping Network programming nightly between 1 and 6 a.m.
In 1990, WPTT-TV and Pittsburgh's News Corporation (not affiliated with the News Corporation that owned Fox until 2013) entered into an agreement to produce a 10 p.m. newscast to air on WPTT-TV which was to begin in the summer of 1991, and would feature news anchors from WTAE-TV. After going through three owners, WPGH-TV was put up for sale again; Sinclair placed a bid for the station in 1991 and won; however, the group struggled to obtain financing. As part of a deal, the group sold WPTT-TV to its operations manager Eddie Edwards (who had been with WPTT-TV since its launch in 1978, and had become best known as host of the station's locally produced public affairs program Eddie's Digest, targeted towards local African-Americans). Soon after, the planned newscast with WPTT-TV was put on hold with an option to either produce it for WPGH-TV, reinstate the plans with WPTT-TV, or cancel it; it was eventually canceled. WPTT-TV also made a deal to increase Home Shopping Network programming hours to at least 15 hours a day with the option of running the programming the entire day. Rumors abounded that WPTT-TV would be running HSN programming for most of, if not the entire day, once the sale was completed. It was already established that some of WPTT-TV's first-run syndicated shows would go to WPGH-TV.
The sales closed on August 29, 1991, with Sinclair acquiring WPGH-TV from Renaissance Broadcasting in the fall of that year. Rights to cash programming from WPTT-TV's schedule were moved to WPGH-TV, while barter shows were returned to syndication distributors (it was thought that WPTT-TV might wind up with some low-budget children's shows to run a couple hours a day). But Eddie Edwards acquired WPTT-TV without programming and began to run Home Shopping Network programming 24 hours a day on WPTT-TV in September, which led to the station being dropped from the market's cable systems. Staffs from both WPGH-TV and WPTT-TV experienced layoffs. Some of WPTT-TV's ex-employees went to WPGH-TV while others stayed at WPTT-TV, and many others were laid off. WPGH-TV kept a decent number of its own staff, taking some from both stations. Edwards then made a deal with Sinclair to buy time on his station from 3 p.m. to midnight (effectively creating one of the first local marketing agreements, which Sinclair would use heavily in its later station acquisitions), and get area cable providers to reinstate WPTT-TV on their lineups.
The deal took effect on January 6, 1992, with WPTT-TV airing cartoons, sitcoms, movies and dramas that Sinclair had no room to air on WPGH-TV. Sinclair's air time on the station expanded in 1993 to begin at noon. In the fall of 1995, WPTT-TV began to run WPGH-TV programming from 6 a.m. to midnight and picked up The Disney Afternoon cartoon block, which had been dropped by KDKA-TV when that station began running CBS' entire lineup.
