 Despite Paramount's partial ownership of DuMont, Paramount's two stations never aired television programs from DuMont's television network (with the exception of KTLA, which ran DuMont programs for one year from 1947 to 1948), and competed against DuMont's affiliates in Los Angeles and Chicago.According to authors Auter and Boyd, Paramount's construction of KTLA and WBKB and its subsequent launch of the Paramount Television Network "undercut" DuMont, a company it had invested in.KTLA began commercial broadcasts on January 22, 1947; its first evening broadcast was hosted by Bob Hope and featured Kirk Douglas, William Bendix, Dorothy Lamour, William Demarest, Ray Milland and Cecil B. DeMille.
