While most people agree that the GoldenAge of comic books began with the introduction of Superman in 1938 in ActionComics #1, there is less agreement about when exactly the GoldenAge endeD、There is a general consensus, however, about the factors that brought the GoldenAge to a close: the rise of the horror comic book in the late 1940s, and the resulting backlash against comic books in the early 1950s.
Superhero comic books reached their peak of popularity in the early 1940s because of all the GIs inEurope and Japan who eagerly read about Superman,Batman, and The Spirit. When these soldiers came home, they still wanted to read comic books, but they sought out more adult content. William Gaines ofEC、Comics was happy to meet the market demand with such grim and gritty titles as Weird Fantasy and TheCrypt of Terror. The creators of superhero comic books, not wanting to be left behind, responded by matching their protagonists against darker criminals in more violent encounters.
These darker comic books aroused the anger of child psychologist Fredric Wertham, who believed that comic books were leading the nation’s youth into crime, violence, and drug abuse. Wertham’s book, The Seduction of the Innocent, was a national best-seller that helped bring about congressional investigations into the corrupting influence of comic books.

These regulations had a numbing effect on the industry.EC、Comics was nearly driven out of the comics business, and the other major players canceled many of their most prominent titles. The comics business did not recover until the Marvel revolution of the early 1960s ushered in the SilverAge.
