What happend to the DuMont-owned networks?
All three are still on the air, and are now O&O stations for existing TV networks. Of the three, only Washington’s WTTG still has its original call signs. New York’s WABD (now WNYW-TV) and D.C.’s WTTG survived as independents before taking up the Fox affiliation in the 1980’s. The stations were later purchased by Rupert Murdoch’s News Corp, making them Fox O&O stations. WDTV in Pittsburgh was sold to Pittsburgh-based Westinghouse Electric. The call signs were immediately changed to KDKA-TV, adopting the same call signs of the radio station in Pittsburgh that became the first commercially-licensed radio station in the world, also owned by Westinghouse. The station also took the CBS affiliation immediately after the sale. Westinghouse’s acquisition of CBS in 1995 made KDKA-TV a CBS O&O station.
