Comic book historians continue to debate the exact boundaries of these eras, but they have come to an agreement, the terms for which originated in the fan press. Comics as a print medium have existed in America since the printing of The Adventures of Obadiah Oldbuck in 1842 in hardcover—making it the first known American prototype comic book. The introduction of Jerry Siegel and Joe Shuster's Superman in 1938 turned comic books into a major industry,[2] 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.[3]
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.
The Silver Age of comic books is generally considered to date from the first successful revival of the dormant superhero form—the debut of Robert Kanigher and Carmine Infantino's Flash in Showcase No. 4 (September/October 1956).[4][5] The Silver Age lasted through the late 1960s or early 1970s,
