Jim Henson and the Muppets' involvement in Sesame Street began when he and Cooney met at one of the curriculum planning seminars in Boston. Author Christopher Finch reported that Stone, who had worked with Henson previously, felt that if they could not bring him on board, they should "make do without puppets".[5] Henson was initially reluctant, but he agreed to join Sesame Street for social goals. He also agreed to waive his performance fee for full ownership of the Sesame Street Muppets and to split any revenue they generated with the CTW.[63] As Morrow stated, Henson's puppets were a crucial part of the show's popularity and it brought Henson national attention.[81] Davis reported that Henson was able to take "arcane academic goals" and translate them to "effective and pleasurable viewing".[82] In early research, the Muppet segments of the show scored high, and more Muppets were added during the first few seasons. Morrow reported that the Muppets were effective teaching tools because children easily recognized them, they were stereotypical and predictable, and they appealed to adults and older siblings.[83]
