Diamond Comic Distributors, Inc. (often called Diamond Comics, DCD, or casually Diamond) is the last remaining comic book distributor serving retailers in North America and worldwide, since the end of the comic book distributor wars in the 1990s. They transport comic books from both big and small comic book publishers, or suppliers, to retailers. Diamond dominates the direct market in the United States, and has a distribution monopoly structured by exclusive arrangements with most major U.S. comic book publishers, including Dark Horse Comics, DC Comics, IDW Publishing, Image Comics, Marvel Comics, and more.
