With no other way to readily obtain cash, DuMont sold WDTV to Westinghouse for $9.75 million in late 1954, after Westinghouse decided to give public backing to the public interest groups for the channel 13 allocation in Pittsburgh and helping to form WQED. While this gave DuMont a short-term cash infusion, it eliminated the leverage the network had to get program clearances in other markets. Without its de facto monopoly in Pittsburgh, the company's advertising revenue shrank to less than half that of 1953. By February 1955, DuMont executives realized the company could not continue as a television network. The decision was made to shut down network operations and operate WABD and WTTG as independent stations.
