Document 6: Sesame Street in the UK: A few months after the 1969 premiere of the children's television program Sesame Street in the U.S., talks began in the United Kingdom to broadcast the programme or develop a co-production on British television. The idea was controversial at the time; the BBC was opposed to it, and ITV was reluctant. Response from parents, educators, and television officials to the show was varied, ranging from distaste to acceptance. After much public debate, the BBC chose not to air "Sesame Street" for several reasons, including the show's educational methods, its creation for American audiences, and the U.K.'s long history of quality educational television programmes for young children. ITV, after much research, including a report entitled "Reactions to Sesame Street in Britain, 1971", chose to air "Sesame Street" on a limited basis. It then switched to Channel 4 in the 1980s and aired there until 2001, when it was pulled from its regular schedule, replaced by "The Hoobs".
