WUSA9

WUSA is a television station in Washington, D.C., affiliated with CBS. It is the flagship station of the Tegna subsidiary of Nexstar Media Group; Nexstar also owns independent station WDVM-TV and CW outlet WDCW. WUSA's studios and transmitter are based at Broadcast House on Wisconsin Avenue in northwest Washington's Tenleytown neighborhood. This station began broadcasting as WOIC on January 16, 1949. It was the fourth station on the air in Washington, D.C., and has been affiliated with CBS since its inception. In June 1950, a joint venture of CBS and The Washington Post purchased WOIC from the Bamberger Broadcasting Service, a subsidiary of R. H. Macy and Company. The station changed call signs to WTOP-TV, marking its association with WTOP radio, and moved into new studios—named Broadcast House—in 1954. That same year, The Post became its sole owner. It was the flagship of what became Post-Newsweek Stations until 1978, when it was traded to the Evening News Association amid increasing pressure to clear away newspaper-broadcast cross-ownership conflicts. The trade came with a call sign change to WDVM-TV.
