Captain Kangaroo is an American children's television series which aired weekday mornings on the American television network CBS for nearly 30 years, from October 3, 1955 until December 8, 1984, making it the longest-running nationally broadcast children's television program of its day. In 1986, the American Program Service (now American Public Television, Boston) integrated some newly produced segments into reruns of past episodes, distributing the newer version of the series until 1993.
The show was conceived and the title character played by Bob Keeshan, who based the show on "the warm relationship between grandparents and children." Keeshan had portrayed the original Clarabell the Clown on The Howdy Doody Show when it aired on NBC. Captain Kangaroo had a loose structure, built around life in the "Treasure House" where the Captain (the name "kangaroo" came from the big pockets in his coat) would tell stories, meet guests, and indulge in silly stunts with regular characters, both humans and puppets.
