Jim Henson was central to the creation of Fraggle Rock and a branch of his media company was wholly responsible for it. https://en.wikipedia.org/wiki/Fraggle_Rock https://en.wikipedia.org/wiki/Fraggle_Rock Sesame Street is a bit different, I believe he was invited to add the Muppets to the show and that these segments were very popular. Still, he wasn't responsible for the show as a whole and didn't have the same role as he and his company had in Fraggle Rock. https://en.wikipedia.org/wiki/Sesame_Street https://en.wikipedia.org/wiki/Sesame_Street
