Entertaining Comics, more commonly known as EC Comics, was an American publisher of comic books specializing in horror fiction, crime fiction, satire, military fiction and science fiction from the 1940s through the mid-1950s, notably the Tales from the Crypt series. In 1954-55, censorship pressures prompted it to concentrate on the humor magazine Mad, leading to the company's greatest success. Initially, EC was privately owned by Maxwell Gaines and specialized in educational and child-oriented stories. Later, during its period of notoriety, it was owned by his son, William Gaines. It was eventually absorbed into the same corporation that later purchased DC Comics and Warner Brothers.
