During the 1960s, the characters—in particular, Kermit and Rowlf the Dog—appeared in skits on several late-night talk shows and on television commercials, including The Ed Sullivan Show. Rowlf became the first Muppet character to appear regularly on network television when he began appearing with Jimmy Dean on The Jimmy Dean Show. In 1966, Joan Ganz Cooney and Lloyd Morrisett began developing a children's educational television program and approached Henson to design a cast of Muppet characters during this stage. Produced by the Children's Television Workshop, the program debuted as Sesame Street in 1969 on NET, and later PBS.
