 With no other way to readily obtain cash , DuMont sold WDTV to Westinghouse Electric Corporation for $ 9 @.@ 75 million in late 1954 . 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 . On April 1 , 1955 , most of DuMont 's entertainment programs were dropped . Bishop Sheen aired his last program on DuMont on April 26 and later moved to ABC . By May , just eight programs were left on the network , with only inexpensive shows and sporting events keeping what was left of the network going through the summer . The network also largely abandoned the use of the intercity network coaxial cable , on which it had spent $ 3 million in 1954 to transmit shows that mostly lacked station clearance . The company only retained network links for live sports programming and utilizing the company 's Electronicam process to produce studio @-@ based programming . Ironically , Electronicam is best remembered for being used by Jackie Gleason 's producers for the 39 @-@ half @-@ hour episodes of The Honeymooners that aired on CBS during the 1955 @-@ 56 television season .
