“DC Comics is the present day publisher of Superman, Batman, Wonder Woman, and other well-known superheroes. DC is the amalgamation of two different publishing concerns: National Comics, which produced Superman and Batman, and sister company All-American Comics, which produced Wonder Woman, Flash, and Green Lantern. The two companies merged in 1944 to form National Periodical Publications, whose comic books bore the “Superman-DC” logo. The publisher was known colloquially as “DC,” which it later adopted as its official name.”
