About WCCO TVWCCO-TV's roots originate with a radio station, but not the one with which it is affiliated today. Radio station WRHM, which signed on the air in 1925, is the station to which WCCO-TV traces its lineage. In 1934, two newspapers—the Minneapolis Tribune and the Saint Paul Pioneer Press-Dispatch—formed a joint venture named "Twin Cities Newspapers", which purchased the radio station and changed its call letters to WTCN. Twin Cities Newspapers later expanded into the fledgling FM band with WTCN-FM, and shortly thereafter to the then-new medium of television with the launch of WTCN-TV on July 1, 1949, becoming Minnesota's second television station, broadcasting from the Radio City Theater at 50 South 9th Street in downtown Minneapolis. Robert Ridder became president of WCCO-TV in 1949. Channel 4 has been a primary CBS affiliate since its sign on. However, it had a secondary affiliation with ABC during its early years, from 1949 to 1953, until a new station using the WTCN-TV calls (now known as KARE-TV) picked up the ABC affiliation, retaining it from its 1953 sign on until 1961 when it became an independent station; it has been affiliated with NBC since 1979.
Twin Cities Newspapers sold off its broadcast holdings in 1952, with channel 4 going to the Murphy and McNally families, who had recently bought the Twin Cities' dominant radio station, WCCO (830 AM), from CBS. The stations merged under a new company, Midwest Radio and Television, with CBS as a minority partner. The call letters of channel 4 were changed to WCCO-TV to match its new radio sister on August 17 (the WTCN-TV call sign appeared again in the market the following year on the new channel 11). CBS was forced to sell its minority ownership stake in the WCCO stations in 1954 to comply with Federal Communications Commission ownership limits of the time.
