Their Sunday entertainment features included the first color comic strip pages, and some theorize that the term yellow journalism originated there, while as noted above the New York Press left the term it invented undefined. The Yellow Kid, a comic strip revolving around a bald child in a yellow nightshirt, became exceptionally popular when cartoonist Richard Outcault began drawing it in the "World" in early 1896. When Hearst predictably hired Outcault away, Pulitzer asked artist George Luks to continue the strip with his characters, giving the city two Yellow Kids. The use of "yellow journalism" as a synonym for over-the-top sensationalism in the U.S. apparently started with more serious newspapers commenting on the excesses of "the Yellow Kid papers".
