Political cartoons were often drawn to show several different stages of the same story. Many of Hogarth's famous political cartoons do this. From this came the idea of telling funny stories in a series of pictures. Comic strips are a type of "cartoon" that is published in newspapers, but they are usually just called "comic strips". Some of the earliest comic strips are The Katzenjammer Kids (1897) and Ginger Meggs (1921). Sometimes they represent like The Beano, Cathy, Baby Blues, Dennis the Menace, Asterix, Peanuts, Cubitus, The Smurfs, Heathcliff and Garfield. Later comic strips from the 1950s onwards show superheros such as Superman and The Phantom. Comic strips well known introduced Superman, Batman, Wonder Woman, Hulk, Spider-Man, X-Men, Fantastic Four and others.
