In May 1970, WAPI-TV became the exclusive NBC affiliate for Birmingham, simultaneously resulting in the CBS programs not already carried by that station moving to WBMG. The switch to an exclusive NBC affiliation was because two of Newhouse Broadcasting's other stations, WSTM-TV in Syracuse and WETM-TV in Elmira, New York (which were then WSYR-TV to be confused with the current WSYR and WSYE-TV respectively), were already affiliated with the network; in addition, the company's chairman was alleged to not have a great personal relationship with CBS president William S. Paley. At the same time that WAPI and WBMG aligned with the respective networks, WCFT-TV (channel 33, now Heroes & Icons affiliate WSES) in Tuscaloosa and WHMA-TV (channel 40, later WJSU-TV and now Heroes & Icons affiliate WGWW) in Anniston, two UHF stations respectively serving the western and eastern portions of Central Alabama, also became full-time affiliates of CBS; like WBMG and WAPI prior to becoming exclusive network affiliates, WCFT and WHMA—both of which signed on the air in the late 1960s—started as affiliates of both CBS and NBC. Prior to that time, the prime time schedules of the Tuscaloosa and Anniston stations virtually mirrored that of WBMG, because of WAPI's exclusive rights to network programming shown on that station for the entire viewing area.
