WSOC was originally locally owned by Carolina Broadcasting, operated by the Jones family, along with WSOC radio (1240 AM, now WYFQ on 930 AM) and WSOC-FM 103.7. WSOC was the second radio station to sign on in Charlotte, having made its debut in 1929, seven years after the debut of WBT (1110 AM). Channel 9 originally operated as a primary NBC affiliate (owing to WSOC radio's affiliation with the NBC Red Network), and maintained a secondary affiliation with ABC, sharing the network with WBTV. In 1959, WSOC-AM-FM-TV were sold to Cox Enterprises under its forerunner, Miami Valley Broadcasting Company. That same year, it dedicated its current studios on North Tryon Street.
