Most of their material takes place in the fictional DC Universe, which also features teams such as the Justice Society of America, the Legion of Super-Heroes, the Suicide Squad, the Justice League and the Teen Titans. The universe features well-known supervillains such as Doctor Sivana, Lex Luthor, The Joker, Catwoman, Scarecrow, Penguin, Two-Face, Cheetah, Vandal Savage, Solomon Grundy, Black Adam, Riddler, the Reverse-Flashes, Captain Cold, Mister Freeze, Brainiac, Bizarro, Gorilla Grodd, General Zod, Sinestro, Poison Ivy, Black Manta, Darkseid, Ra’s al Ghul, Deathstroke, Doomsday, Harley Quinn and Bane. The company has also published non-DC Universe-related material, including Watchmen, V for Vendetta, and many titles under their alternative imprint Vertigo.
The initials "DC" came from the company's popular series Detective Comics, which featured Batman's debut and subsequently became part of the company's name. Originally in Manhattan at 432 Fourth Avenue, the DC Comics offices have been located at 480 and later 575 Lexington Avenue; 909 Third Avenue; 75 Rockefeller Plaza; 666 Fifth Avenue; and 1325 Avenue of the Americas. DC had its headquarters at 1700 Broadway, Midtown Manhattan, New York City, however DC Entertainment relocated its headquarters from New York to Burbank, California in April 2015.
Random House distributes DC Comics' books to the bookstore market, while Diamond Comic Distributors supplies the comics shop specialty market. DC Comics and its longtime major competitor Marvel Comics (acquired in 2009 by The Walt Disney Company, WarnerMedia's main competitor) together shared approximately 70% of the American comic book market in 2017, though this number may give a distorted view since graphic novels are excluded. With the sales of all books included, DC is the second biggest publisher, after Viz Media, and Marvel is third. Wikipedia
