Sesame Street is an American children`s television program that is known for its use of format and structure to convey educational concepts to its preschool audience. It utilizes the conventions of television, in the form of a combination of Jim Henson`s Muppets, animation, short films, humor and cultural references. Since its premiere in 1969, it was the first preschool educational television program to base its contents, format and production values on laboratory and formative research. It was also the first to include a curriculum "detailed or stated in terms of measurable outcomes".
