The Muppets are an American ensemble cast of puppet characters known for an absurdist, burlesque, and self-referential style of variety-sketch comedy. Created by Jim Henson in 1955, they are the focus of a media franchise that encompasses television, film, music, and other media associated with the characters. Originally owned by the Jim Henson Company for nearly five decades, the franchise was purchased by the Walt Disney Company in 2004.
