 In August , Paramount , with the help of other stockholders , seized full control of DuMont Laboratories . The last non @-@ sports program on DuMont , the game show What 's the Story , aired on September 23 , 1955 . After that , DuMont 's network feed was used only for occasional sporting events . DuMont 's last broadcast , a boxing match , aired on August 6 , 1956 . The date has also been reported as April 1950 , September 1955 , or August 4 , 1958 . According to one source , the final program aired on only five stations nationwide . It appears that the boxing show was syndicated to a few other east coast stations until 1958 , but likely not as a production of DuMont or its successor company .
