Twin Cities Newspapers expanded to television broadcasting with the launch of WTCN-TV on channel 4 on July 1, 1949 from the Radio City Theater at 9th Street and LaSalle Avenue, becoming the second modern television station in the state after KSTP-TV took to the air a year earlier. WTCN moved from the Wesley Tower to Radio City in September 1949 and sometime during this period, possibly at the same time; its FM sister was housed there, too. However, WTCN-TV 4 was short-lived. Twin Cities Newspapers decided to sell both of the WTCN radio stations and purchase a majority share of WCCO Radio from CBS three years later; the TV station's call letters were changed to match the newly acquired radio station on August 17, 1952. A new company, Midwest Radio and Television, was formed as a holding company for the WCCO stations; it was later spun off to the Murphy and McNally families. Both WCCO stations are currently owned by CBS directly. This TV station has always had a primary CBS affiliation, an affiliation that has remained consistent to this day (although it aired ABC programming as a secondary affiliation in its early years). WCCO-TV 4 remained at the 9th Street location until 1983, when it moved to Nicollet Mall at 11th Street.
