Archer and a History of Underground Comix

In his “On Archer’s Underground Comix Roots,” Charles Bock discusses the history of adult Comix and how they laid the foundation for cartoons like The Simpsons and Archer. Bock claims:

Comix. That sudden x. In 1958 the Motion Picture Association of America slapped Xs on what it determined to be adults-only fare. In the late Sixties, the x provided the fledgling cartooning genre with separation from “legitimate” comic books, the crossed final letter offering both warning and thrill… The young artists were ravenous to test their abilities; like the era’s emerging postmodern fiction writers, they were fluent in their chosen medium and knowledgeable about contemporary art and art history. They were also tripping balls.
