de facto affiliate for the Wheeling, West Virginia/Steubenville, Ohio market. Although it is still carried on area cable systems, CBS affiliate WTRF-TV added a primary Fox and secondary MyNetworkTV affiliation on a new digital subchannel; sister station WTOV-TV later acquired the Fox affiliation for their second subchannel in 2014. It can also be seen in some parts of the Clarksburg/Weston/Morgantown, West Virginia market, even though that area is served by WVFX. On May 15, 2012, Sinclair Broadcast Group and Fox agreed to a five-year extension to the network's affiliation agreement with Sinclair's 19 Fox stations, including WPGH-TV, allowing them to continue carrying Fox programming through 2017. Since acquiring the rights to the NFL's NFC broadcasts in 1994, WPGH-TV normally airs two Pittsburgh Steelers games each season (when they host an NFC team at Heinz Field). A change in the NFL broadcasting contracts for the 2014 NFL season allowing cross-network flex-scheduling allows WPGH-TV the opportunity to broadcast more Steelers games, but as of 2017, the NFL has not yet cross-flexed a Steelers game from CBS (KDKA-TV, in turn) to Fox (and to WPGH, in turn). The Steelers 2018 Sunday night matchup with the Oakland Raiders, however, was flexed out into the afternoon and will air on Fox, giving WPGH-TV its first all-AFC Steelers matchup. Averted loss of Fox affiliation On May 8, 2017, Sinclair announced that it would acquire Tribune Media for $3.9 billion. The deal is expected to receive FCC approval sometime in the first half of 2018. The deal has brought concerns by Fox who see Sinclair as a competitor towards conservative-leaning news, as well as increased leverage by Sinclair on reverse compensation to air Fox programming. On August 2, 2017, it was reported that Fox Television Stations was in talks with Ion Media to create a joint venture that would own their respective stations. The partnership was said to include plans to shift affiliations from Sinclair stations in favor of Ion-owned stations, such as those whose affiliation agreements are soon to expire. In Pittsburgh's case, this would include shifting Fox from WPGH-TV to WINP-TV, which would mark the first Big Four television network affiliation switch in the Pittsburgh market since Westinghouse Electric Corporation purchased KDKA-TV (then WDTV) from the DuMont Television Network in late 1954 and dropping that station's DuMont programming for CBS, and the first threat of a Big Four affiliation change since Westinghouse mulled switching KDKA-TV
