The network experimented with television in the early 1930s, launching experimental station W6XAO in Los Angeles, California, on December 31, 1931. It broadcast one hour per day throughout the 1930s. In 1937, the TV and radio operations teamed up to broadcast the opening of the 27th annual Los Angeles Motor Car Dealers' Automobile Show. Don Lee also annually televised the
Tournament of Roses Parade. In 1939, W6XAO's transmitter (along with the studios) were moved to the top of
Mount Lee, greatly increasing the range of the station. World War II brought a halt to further development of television, although W6XAO continued limited broadcasts throughout the war. W6XAO was commercially licensed in May 1948, when it became KTSL. == New building ==
