The Muppets are a group of puppet characters created by Jim Henson. Individually, a Muppet is properly one of the puppets made by Jim Henson or his Company's workshop – though the term is often used erroneously to refer to any puppet that resembles the distinctive style of The Muppet Show and Sesame Street characters, the term is both an informal name and legal trademark linked to the characters created by Henson
a US television programme in which the main characters were puppets such as Kermit the Frog and Miss Piggy. The characters, who were made by Jim Henson, are called Muppets, and they perform in amusing sketches (=short scenes) with well-known human entertainers. Some of the muppets also appear in the children's programme Sesame Street
