Sesame Workshop (SW), originally known as the Children's Television Workshop (CTW) is an American non-profit organization for the research and production of educational children's programs. It established in 1968.
The Workshop oversaw the production of Sesame Street, a television show for pre-school children from low-income families. Two years were spent, from 1966 to 1968, researching, developing, and raising money for the new show. It was called "one of the most important television developments of the decade".
