American comics developed out of such magazines as Puck, Judge, and Life. The success of illustrated humour supplements in the New York World and later the New York American, particularly Outcault's The Yellow Kid, led to the development of newspaper comic strips. Early Sunday strips were full-page and often in colour. Between 1896 and 1901 cartoonists experimented with sequentiality, movement, and speech balloons.
