Captain Kangaroo was a children's television series which, in one form or another, ran from 1955 until 1984 on CBS and was later re-run on PBS. Created by and starring Bob Keeshan, the series combined comedy skits with nature lessons, story reading, animated segments, and puppet characters.
Though the series was not designed to follow a specific educational curriculum, elements of the Captain Kangaroo format influenced the development of Sesame Street. This was in no small part due to the fact that many of the key members of the Children's Television Workshop, including Dave Connell and Jon Stone, had previously worked on the series. Episodes of Captain Kangaroo were studied to test children's attention spans and to help develop the CTW model. 
When scheduling the first season of Sesame Street, Joan Ganz Cooney and associates deliberately avoided the 8 a.m. timeslot occupied on CBS by Captain Kangaroo, so as not to be in direct competition with what CTW viewed as the only worthwhile network children's show.
