DC Comics is one of the largest American companies in comic book and related media publishing. A subsidiary of Time Warner, DC is responsible for such famous characters as Superman, Batman, Wonder Woman, Green Lantern, The Flash, Aquaman and their teammates in the Justice League. For decades, DC Comics has been one of the two largest American comic book companies, along with Marvel Comics. The initials "DC" were originally an abbreviation for Detective Comics, and later the official name.
Originally located in New York City at 432 Fourth Avenue, DC has been successively headquartered at 480 and later 575 Lexington Avenue; 909 Third Avenue; 75 Rockefeller Plaza; 666 Fifth Avenue; and 1325 Avenue of the Americas (in 1992). DC took over several floors when it moved to 1700 Broadway in the mid-1990s, relocating there with fellow Time Warner property MAD Magazine, which moved there from 485 Madison Avenue.
