The Johnson Family put Austin's first TV station on the air in 1952, Channel 7 KTBC-TV. A co-owned FM station signed on the air in 1960, 93.7 KTBC-FM (now KLBJ-FM). In the 1950s, as network programming moved to television, 590 KTBC began playing middle of the road (MOR) and easy listening music, while still airing CBS News on the hour. In 1973, the call letters were changed to KLBJ and KLBJ-FM, to match the initials of former President Johnson, who had died earlier that year. The AM station continued its format of MOR music with news, talk and sports. The year before, the FM station had switched to a pioneering Progressive Rock sound.
