KTBC-TV, the first television station in Austin and Central Texas, began broadcasting on Thursday, November 27, 1952. It was owned by the Texas Broadcasting Company, which was owned by Senator Lyndon B. Johnson and his wife Lady Bird, along with KTBC radio (590 AM and 93.7 FM). Lady Bird used her inheritance to purchase the station and remained actively involved with her radio station until well into her eighties, making her the first president's wife to become a millionaire on her own. KTBC-TV carried programming from all four major networks at the time: ABC, CBS, NBC, and DuMont. However, it was primarily affiliated with CBS, airing approximately 65% of the network's schedule. The remaining coverage was split between NBC and ABC.
