It is produced by Sesame Workshop (known as the Children's Television Workshop (CTW) until June 2000) and was created by Joan Ganz Cooney and Lloyd Morrisett. The program is known for its images communicated through the use of Jim Henson's Muppets, and includes short films, with humor and cultural references. The series premiered on November 10, 1969, to positive reviews, some controversy, and high viewership; it has aired on the US's national public television provider PBS since its debut, with its first run moving to premium channel HBO on January 16, 2016, then its sister streaming service HBO Max in 2020.
