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.
4Kids TV
Most of Fox's owned-and-operated stations opted to carry 4Kids TV, these were mainly stations that had been owned by the network since Fox launched in October 1986 or were Fox charter affiliates that Fox Television Stations had acquired since that point. However dating back to the existence of the Fox Kids block, the twelve stations that Fox acquired from New World Communications in 1996 (and had earlier affiliated with the network through a 1994 multi-station affiliation deal—which prior to then, had been affiliated with ABC, NBC or CBS) generally did not air 4Kids TV. In some of the New World markets, 4Kids was not carried on any station. In a majority of these markets, an independent station carried the block; in others, it was carried by either a UPN, or later, a CW or MyNetworkTV affiliate. The lone exception was in St. Louis, Missouri, where Fox O&O (now affiliate) KTVI carried the block (although it aired 4Kids TV two hours earlier that the network's recommended scheduling for the block, beginning at 5:00 a.m., due to the station's Saturday morning newscast).
