In 1944, the "Republic" sold KTAR to Chicago, Illinois advertiser John J. Louis Sr., of Needham, Louis, and Brorby. In 1955, Louis bought two-year-old KTYL-TV (channel 12), Phoenix's second television station, from Harkins Theatres, and changed the call letters to KVAR. In 1959, after the FCC allowed stations in different cities of license to hold the same call letters, KVAR became KTAR-TV. The same year, the stations moved to a new studio on Central Avenue in Phoenix. The Louis family bought several other broadcasting interests in the 1960s. Eventually, the Louis broadcasting interests became known as Pacific & Southern Broadcasting, headquartered in Phoenix with KTAR-AM-FM-TV as the flagship stations.
