WPNT (channel 22) is a television station in Pittsburgh, Pennsylvania, United States, affiliated with The CW and MyNetworkTV. It is owned by Sinclair Broadcast Group alongside Fox affiliate WPGH-TV (channel 53). The two stations share studios on Ivory Avenue in the city's Summer Hill section, where WPNT's transmitter is also located.

The channel 22 allocation dates back to the 1950s, and was initially acquired by public interest groups as a "backup" plan if the groups were not able to acquire the channel 13 allocation for public television. The groups were in a battle with locally based Westinghouse Electric Corporation (owners of KDKA radio), who wanted the channel 13 allocation for the proposed KDKA-TV. However, as Westinghouse later gave the groups their blessing to use channel 13 for what would become WQED (Westinghouse bought WDTV from struggling DuMont and transformed that station into KDKA-TV instead), WQED was now stuck with two TV licenses but found use in possibly using channel 22 for educational programs it did not have time to air.

WQED planned to use its proposed WQEX on channel 22, but as fate would have it WENS-TV (channel 16) lost its tower in Reserve Township in a storm on March 11, 1955, leading to a channel sharing agreement with WQED until the tower could be fixed. As WENS-TV was already in a battle for survival competing for the channel 11 license that it would ultimately lose, WQED was able to acquire WENS-TV's assets after that station signed off in 1957 and use its construction permit for channel 22 to relaunch WENS-TV as WQEX on channel 16 instead. (That station is now WINP-TV.) Its channel 22 license and some intellectual property from WENS-TV would eventually be sold to the Commercial Radio Institute (which later became Sinclair Broadcast Group) for the current channel 22, outbidding Cornerstone Television, who ended up with the channel 40 license to launch WPCB-TV.

Rising out of the ashes of WENS-TV, channel 22 finally signed on the air on September 26, 1978, as WPTT-TV (which stood for Pittsburgh Twenty-Two, referencing the UHF channel on which it broadcast), the market's second commercial independent station and its fourth UHF station (after WPGH-TV). It started out running a number of popular off-network sitcoms from the 1950s and 1960s, off-network dramas and westerns, very old movies and network programming preempted by WTAE-TV (channel 4), KDKA-TV (channel 2) and WIIC-TV (channel 11, now WPXI). For a time, WPTT-TV aired the children's television program Captain Pitt, which featured older cartoon shorts.

WPTT-TV also originated more of its own local programming with Prize Bowling, which originally began as Bowling for Dollars on ABC network competitor WTAE-TV for many years until host Nick Perry was jailed for a lottery broadcast scam. The succeeding host was not received well by viewers, and the show ended up being canceled. WPTT-TV took the opportunity to fill the void in the market with Prize Bowling, first hosted by Pittsburgh radio legend Roger Willoughby-Ray and then by Pittsburgh Steelers announcer Jack Fleming. The show's success was modest at best, and was canceled after two years. Other programs of varying degrees of success were The Ghost Host, Eddie's Digest and Studio Wrestling.

The station also aired a newscast in the early 1980s, a rarity at this time for stations not affiliated with the then-major networks (ABC, CBS and NBC). This newscast was called WPTT News, and in the opening segment, the letters "news" were formed from a compass indicating the four cardinal directions. This opening segment, featuring then-anchorman Kevin Evans, appeared briefly (and was audible) in the movie Flashdance during a scene where Jennifer Beals' character returns home and turns on the television. The presentation was relatively low-budget, with the anchor simply reading copy, with no field video shots other than the weather read over a stock video shot denoting the conditions outside, and was not a factor in taking ratings away from then-market laggard WIIC-TV, much less solid runner-up WTAE-TV and then-locally-owned Group W powerhouse KDKA-TV. As sister stations WBFF in Baltimore did not air newscasts until 1991 and WTTE in Columbus, Ohio, would not air any newscasts from its 1984 sign-on until Sinclair purchased ABC affiliate WSYX in 1996, this marked Sinclair's first foray into local news, a genre it would become much more involved in from the mid-1990s on.

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.^{[citation needed]}
