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.
WCIX
On December 3, 2018, Nexstar announced it would acquire the assets of Chicago-based Tribune Media for $6.4 billion in cash and debt. The deal—which would make Nexstar the largest television station operator by total number of stations upon its expected closure late in the third quarter of 2019—would result in WCIX and WCIA gaining additional sister stations in nearby markets including Chicago (independent station WGN-TV) and St. Louis (Fox affiliate KTVI and CW affiliate KPLR-TV). (Ownership conflicts exist in two existing Nexstar markets involving Nexstar's duopoly of CW affiliate WISH-TV and MyNetworkTV affiliate WNDY-TV and Tribune's duopoly of Fox affiliate WXIN and CBS affiliate WTTV/WTTK in Indianapolis and Nexstar's virtual triopoly of CBS affiliate WHBF-TV, CW affiliate KGCW and Fox-affiliated SSA partner KLJB and Tribune-owned ABC affiliate WQAD-TV in the Quad Cities.)
