Input: Question: How long before the debut on "Sesame Street" had Jim Henson created the Muppets? Passage:Since its debut in 1969, Sesame Street had given Jim Henson's Muppet characters exposure; however, Henson began to perceive that he was becoming typecast as a children's entertainer. Subsequently, he began conceiving a programme for a more adult demographic. Two television specials, The Muppets Valentine Show (1974) and  (1975), were produced for ABC and are considered pilots for The Muppet Show. Neither of the two specials was ordered to series. However, the prime-time access rule was recently enacted, shifting the 7:30 to 8 pm ET slot from the networks to their affiliates. CBS became interested in Henson's series proposals and expressed intent to broadcast it weekly on its owned and operated stations. According to the original pitch reel, George Schlatter was originally involved.
