The introduction of Jerry Siegel and Joe Shuster's Superman in 1938 turned comic books into a major industry, and is the start of the Golden Age of comics. Historians have proposed several names for the Age before Superman, most commonly dubbing it the Platinum Age. While the Platinum Age saw the first use of the term "comic book" (The Yellow Kid in McFadden's Flats (1897)), the first known full-color comic (The Blackberries (1901)), and the first monthly comic book (Comics Monthly (1922)), it was not until the Golden Age that the archetype of the superhero would originate.
