DC Comics is one of the two largest American companies in comic book and related media publishing (the other being Marvel Comics). Today a subsidiary of Time Warner, DC is responsible for pop culture icons such as Superman, Batman, Wonder Woman, and their teammates in the Justice League.
The company was originally called National Periodical Publications (and credited as such in early animation projects, including some of the early Super Friends series). The DC imprint first saw use in 1940, and became the company's official name in the 1970s. The initials "DC" are an abbreviation for Detective Comics, after one of the company's flagship titles. DC Comics' main office is in New York City, though they have offices in Los Angeles as well.
