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.
KTVK
On May 23, 1994, New World Communications announced an affiliation deal with Fox in which twelve of its stations—including Phoenix's longtime CBS affiliate KSAZ-TV—would defect from their affiliations with ABC, CBS and NBC to join Fox. CBS approached KTVK for an affiliation, but the Lewises turned the offer down, expecting a renewed pact with ABC. Much to the Lewises' surprise though, the E. W. Scripps Company forced ABC to move its Phoenix area affiliation to the company's then-Fox affiliate KNXV-TV (channel 15) as a condition of retaining ABC on the company's two biggest stations, WEWS in Cleveland and WXYZ-TV in Detroit, which were both approached by CBS themselves to replace stations that also switched to Fox in the New World deal. KTVK then approached CBS in an effort to secure that network affiliation, but Meredith Corporation, owner of then-independent future-sister station KPHO-TV (channel 5), convinced CBS to move its affiliation there as a condition of keeping the CBS affiliation on its Kansas City station KCTV.
