Penguin Random House Publisher Services distributes DC Comics' books to the bookstore market, while Diamond Comic Distributors supplied the comics shop direct market until June 2020, where Lunar Distribution and UCS Comic Distributors, who already distributed to the direct market due to Diamond's distribution interruption as a result of the COVID-19 pandemic, replaced Diamond to distribute to that 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.
