The Muppets, who’ve had their own television show as well as a series of movies, are best known for their roles on Sesame Street, which first appeared in 1969.
After 4,100 episodes, Sesame Street is the longest running television show in history and has received more Emmy Awards than any other show.
The Muppets were Jim Henson’s idea, and he named them by combing the words marionette and puppet.
