WUTV
On December 6, 2017, it was reported that Sinclair and Fox were working on a deal that would see its Fox affiliates renew their affiliation agreement in exchange for Sinclair selling some of its Fox affiliates directly to Fox Television Stations. The deal would see between six and ten Fox affiliates owned by Sinclair and Tribune (all in markets with an NFL team) become Fox owned-and-operated stations. It is not known if WUTV will be one of the stations sold, although the stations being sold to Fox are expected to be from Tribune Media (notably KCPQ in Seattle, where Sinclair already owns KOMO-TV), many of which were previously owned by Fox. A sale to Fox would make WUTV Buffalo's first Big Four network O&O since WBUF-TV (channel 17, now PBS member WNED-TV), which was owned by NBC from 1955 until its sign-off in 1958. On May 9, 2018, Sinclair announced that seven Fox affiliates would be sold to FTS, but WUTV was not included and an affiliation renewal was announced for that station instead, keeping WUTV with Sinclair.
KDAF
In May 1985, Metromedia reached an agreement to sell KRLD-TV and its five sister independent stations – WNEW-TV (now WNYW) in New York City, KTTV in Los Angeles, WFLD-TV in Chicago, WTTG in Washington, D.C. and KRIV in Houston – to News Corporation for $2.55 billion (ABC affiliate WCVB-TV in Boston, the company's only network-affiliated station, would be sold to the Hearst Broadcasting subsidiary of the Hearst Corporation for $450 million in a separate, concurrent deal as part of a right of first refusal related to that station's 1982 sale to Metromedia). KRLD (AM) was sold to CBS Radio, to which Metromedia had previously attempted to sell the station in 1984, prior to its obtainment of the cross-ownership waiver for it and KRLD-TV.
That October, News Corporation – which had purchased a 50% interest in 20th Century Fox corporate parent TCF Holdings for $250 million in March 1985 – announced its intentions to create a fourth television network that would use the resources of 20th Century Fox Television to both produce and distribute programming, intending for it to compete with ABC, CBS and NBC. The company formally announced the launch of the new network, the Fox Broadcasting Company, on May 7, 1986, with the former Metromedia stations serving as its nuclei. The purchase of the Metromedia stations was approved by the FCC and finalized on March 6, 1986, with News Corporation creating a new broadcasting unit, the Fox Television Stations, to oversee the six television stations. Concurrent with the completion of the Metromedia stations' acquisition by News Corporation, the station's call letters were changed to KDAF (representing the two cities it served, Dallas and Fort Worth," but would later take on an unofficial secondary meaning as "Dallas Area Fox").
