At one time, American General was the parent company of the Life and Casualty Insurance Company based in Nashville, former owner of WSM-TV rival WLAC-TV (now WTVF ), and WLAC-AM-FM, but divested the broadcast properties in 1975, long before the NLT merger. American General was not interested in NLT's non-insurance operations, and sold WSM, Inc. (which included Opryland Hotel , Opryland USA , Ryman Auditorium , The Grand Ole Opry ,
992-490: The Federal Radio Commission implemented General Order 40 , which assigned WSM to a frequency of 650 kHz, as Tennessee's sole "clear channel" allocation. In 1932, the station boosted its power to 50,000 watts. On September 30, 1950, WSM added a television sister station on channel 4, operating as a primary NBC affiliate; WSM-TV was Nashville's first TV station. The studios remained in its original location until
