 ABC had more luck with its new filmed series, "The Adventures of Ozzie and Harriet", while CBS aired the filmed "Our Miss Brooks".Another successful CBS filmed show was anthology series "Four Star Playhouse", which although not a top-rated show, did prove popular enough to run to 1956.Fall 1952 was a major blow for DuMont, when the network's biggest star, Jackie Gleason, moved from DuMont to CBS.
