highest radiated power of any radio station worldwide, operating at 500,000 watts; after the FM station suspended operations in June 1948 due to continued revenue losses due to the lack of radios equipped with FM tuners, Hanna borrowed $150,000 to build a new studio facility and transmitter atop Red Mountain for the television station. In September 1950, WBRC established a coaxial cable link with fellow NBC-DuMont affiliate WRGB (now a CBS affiliate) in Schenectady, New York, allowing the station to broadcast NBC and DuMont network programs both live and live-to-air. On February 19, 1953, WBRC-TV moved to channel 6 as part of a frequency realignment ordered by the FCC, resulting from the Sixth Report and Order issued the year prior in 1952. This move was made to alleviate signal interference problems between WBRC and WSM-TV (now sister station WSMV-TV) in Nashville, which also transmitted on channel 4, that were present in portions of northern Alabama. Later that year, Hanna also sold the WBRC television and radio stations to Storer Broadcasting for $2.3 million—a handsome return on her first husband's purchase of WBRC radio 25 years earlier. George B. Storer, the company's founder and chairman, was a member of the board of directors at CBS, and most of his television stations were affiliates of that network. Storer may have used his leverage to secure a primary CBS affiliation for WBRC-TV, which joined the network on July 4, 1954. NBC programming subsequently moved to channel 13 (by then, using the call sign WABT); both stations, however, retained a secondary affiliation with ABC. On September 17 of that year, the WBRC stations moved to a new, much larger studio facility located on Red Mountain that was built by Storer, where channel 6 continues to operate from to this day. The building, like many of those built by Storer to serve as studios for its broadcast properties, resembled an antebellum mansion. While it may have been out of place in most of Storer's other markets (many of which were located outside of the Southern United States), it was a perfect fit for Birmingham. Unusual for a commercial broadcaster, Storer supported educational television, and the company donated two transmitters and frequencies in the Birmingham market (channels 7 and 10, which were respectively occupied by WCIQ and WBIQ when both stations signed on in 1955) to Alabama Educational Television (now Alabama Public Television). This also, however,
