 Like WABD and DuMont's other owned-and-operated station, WDTV in Pittsburgh, WTTG was far more successful than the network as a whole.In 1956, after DuMont shut down network operations, WTTG and WABD became independent stations and were spun off from DuMont Laboratories as the DuMont Broadcasting Corporation (WDTV was sold to Westinghouse Electric Corporation the previous year; it is now CBS owned-and-operated station KDKA-TV).DuMont later changed its name to Metropolitan Broadcasting in order to distance itself from its former parent company.
