The current incarnation of Feud started on WOIO for an hour in Cleveland. At the start of season 3, Feud went to WOIO's sister station, WUAB. The 4th season saw Feud end up on WKYC for an hour at 2:05 AM. WVPX got the second part of the Feud's double run starting this past season. And on the 13th, the Feud returns where it began, on WOIO for an hour. My TiVo also lists WVPX as airing an episode at 7 PM, not the network-wide ep. as that airs at 7:30.
In sum...
Season 1: WOIO
Season 2: WOIO
Season 3: WUAB
Season 4: WKYC
Season 5: WKYC and WVPX
Season 6: WOIO (and WVPX?)
Add in the previous incarnations of the Feud and every current English language, for profit station in Cleveland has aired the Feud. (WEWS--ABC daytime, WJW--CBS daytime, WBNX--Dawson's return in 1994)
