Comics as a medium gained increasing popularity during and immediately after the second World War with soldiers getting hooked on reading them, as such companies (most notably EC) began to produce more mature and violent comics to satisfy demand, this mixed with the growing popularity of super hero brought increased attention to the medium. A psychiatrist Fredrick Wertham began a study into what he saw as the negative effects of comic books on children and wrote articles for several magazines such as Ladies' Home Journal and wrote a book on the topic, Seduction of the Innocent. He claimed that there were direct correlations between children reading comics and growing up to be gay, violent criminals. His book made several wild claims from sexual subtext hidden in comics, Superman being both un-American and a fascist, the gay undertones of Batman & Robin's relationship as well as Wonder Woman's with her Holiday Girls, the coining of the term "headlight covers" that referred to female character's having their breasts prominently display. He especially went after the horror comics of EC such as Tales from the Crypt, especially citing decapitations and 'injury to eye' panels, of which he provided panel examples of in his book. With the release of his personal papers and details of his study released by the Library of Congress in 2010 it was discovered that much of his findings and the correlations he made were falsified and exaggerated.
His crusade gained popularity and his argument against comics were event brought to Congress in 1954 which lead to the formation of the Comics Code Authority that heavily censored comics for decades and the cancelation of several titles and shuddering EC's comic business, the only surviving title being MAD Magazine since it was classified as a magazine and not a comic book. The criteria of the code stated:
- Crimes shall never be presented in such a way as to create sympathy for the criminal, to promote distrust of the forces of law and justice, or to inspire others with a desire to imitate criminals.
- If crime is depicted it shall be as a sordid and unpleasant activity.
- Policemen, judges, government officials, and respected institutions shall never be presented in such a way as to create disrespect for established authority.
- Criminals shall not be presented so as to be rendered glamorous or to occupy a position which creates a desire for emulation.
- In every instance good shall triumph over evil and the criminal punished for his misdeeds.
- Scenes of excessive violence shall be prohibited. Scenes of brutal torture, excessive and unnecessary knife and gunplay, physical agony, the gory and gruesome crime shall be eliminated.
- No comic magazine shall use the words "horror" or "terror" in its title.
- All scenes of horror, excessive bloodshed, gory or gruesome crimes, depravity, lust, sadism, masochism shall not be permitted.
- All lurid, unsavory, gruesome illustrations shall be eliminated.
- Inclusion of stories dealing with evil shall be used or shall be published only where the intent is to illustrate a moral issue and in no case shall evil be presented alluringly, nor so as to injure the sensibilities of the reader.
- Scenes dealing with, or instruments associated with walking dead, torture, vampires and vampirism, ghouls, cannibalism, and werewolfism are prohibited.
- Profanity, obscenity, smut, vulgarity, or words or symbols which have acquired undesirable meanings are forbidden.

- Nudity with meretricious purpose and salacious postures shall not be permitted in the advertising of any product; clothed figures shall never be presented in such a way as to be offensive or contrary to good taste or morals.
Over time the code was slightly updated and some of it's guidelines relaxed, such as the inclusion of stories of monsters and other supernatural entities if they came from a background of 'literary merit' such as Frankenstein's Monster or Dracula and the allowance of the topic of drugs and substance abuse, but only if they were shown as an addiction and shown in a negative light. After the start of the new millennium publishers finally began to abandon the code in favor of self policing their own books and posting age guidelines on the books themselves, with the Comics Code becoming officially defunct in 2011 which Archie Publishing was the last company to stop using it.
