Sesame Workshop, formerly known as the Children's Television Workshop (CTW), is a Worldwide American non-profit organization behind the production of several educational children's programs that have run on public broadcasting around the world (including PBS in the United States). Sesame Workshop was instrumental in the establishment of education children's television in the 1960s, and continues to provide grants for educational children's programming four decades later. Joan Ganz Cooney and Lloyd Morrisett were the original founders, with the intention of producing a revolutionary television series based on cutting-edge research into childhood learning. The result was Sesame Street, a landmark program which has been reproduced in countries around the world.

Although it was originally funded by the Carnegie Corporation and the United States Office of Education, the majority of the Workshop's funding is now earned through licensing the use of their characters to a variety of corporations to use for books, toys, and other products marketed toward children. This ensures that the Workshop has reliable access to funding for its programming without depending on unpredictable grants.
