Howdy Doody is an American children's television program (with circus and Western frontier themes) that was created and produced by Victor F. Campbell and E. Roger Muir. It was broadcast on the NBC television network in the United States from December 27, 1947, until September 24, 1960. It was a pioneer of children's programming and set the pattern for many similar shows. One of the first television series produced at NBC in Rockefeller Center, in Studio 3A, it pioneered color production in 1956 and NBC (then owned by RCA Television) used the show to promote color television sets in the late 1950s.
