Like all of the WLW television stations in Ohio, WLWC was an NBC affiliate, though it carried some programming from the DuMont network until WTVN-TV (now WSYX) took the DuMont affiliation when that station launched in September 1949. In 1952, following the release of the Federal Communications Commission (FCC)'s "Sixth Report and Order" which ended the four-year freeze on station license awards, a VHF frequency realignment resulted in WLWC being forced to move to channel 4, trading channels with then-NBC-owned WNBK (now WKYC) in Cleveland; the switch took place in June 1953.
