Sesame Workshop, originally the Children's Television Workshop, is the American non-profit organization behind the production of Sesame Street, now in its 47th consecutive season on the public broadcasting channel PBS. In 1966 Joan Ganz Cooney and Lloyd Morrisett began researching a television show to help children, especially those from low-income families, prepare for school. Sesame Street premiered in 1969. Cooney credited "educational advisers, researchers, and television producers ... as equal partners" in the show's success. The early 1980s were a challenging period for the Workshop; the end of government funding, difficulty in finding audiences for their other productions, and a series of bad investments hurt the organization until 1985, when licensing agreements had stabilized revenues. The organization expanded into other areas, including books and music, international co-productions, outreach programs to preschools, and interactive media and new technologies. By 2005, income from international co-productions of the show was $96 million, and by 2008, the Sesame Street Muppets accounted for $15–17 million per year in licensing and merchandising fees.
