This series of interviews traces the development of the Children's Television Workshop and the creation of "Sesame Street" in the words of some of those principally responsible. They recall 1966 discussions of how television might be made to serve preschool children, preliminary studies, the roles of the Carnegie Corporation, of Harold Howe II as United States Commissioner of Education, and of the Ford Foundation in advancing the concept and helping finance it, the founding of the Workshop and its staffing, and the emergence of the Sesame Street format, as well as the changing relationship of the Workshop with National Educational Television, from which it became independent.
