Penguin Random House will stop distributing to direct-market comic book stores though Diamond Comic Distributors, Bleeding Cool reports. In a letter to retailers, PRH writes, “Going forward, all Penguin Random House sales into the US Direct Market will be handled by our in-house sales team.” Any titles with an on-sale date after June 25 will be handled by PRH. Marvel, Dark Horse, and IDW titles had previously been sub-distributed by Diamond. The move follows Diamond’s rollercoaster Chapter 11 bankruptcy process.
