 The DuMont Television Network ( also known as the DuMont Network , simply DuMont / Du Mont , or ( incorrectly ) Dumont / duːmɒnt / ) was one of the world 's pioneer commercial television networks , rivalling NBC and CBS for the distinction of being first overall in the USA . It began operation in the United States in 1946 . It was owned by DuMont Laboratories , a television equipment and set manufacturer . The network was hindered by the prohibitive cost of broadcasting , by regulations imposed by the Federal Communications Commission ( FCC ) which restricted the company 's growth , and even by the company 's partner , Paramount Pictures . Despite several innovations in broadcasting and the creation of one of television 's biggest stars of the 1950s ( Jackie Gleason ) , the network never found itself on solid financial ground . Forced to expand on UHF channels during an era when UHF was not yet a standard feature on television sets , DuMont fought an uphill battle for program clearances outside of their three owned @-@ and @-@ operated stations in New York , Washington and Pittsburgh , finally ending network operations in 1956 .
