Diamond, the company that has a monopoly on the comic book market, has released their sales statistics for August 2017 and it's not good. Compared to August 2016, shipments were down 26% and retailers spent 21% less on comics. Comichron calculated that $45.7 million in product shipped, down from the previous August's 21st century record of $57.7 million. August 2016 saw the release of DC's Rebirth. Looks like publishers will just have to relaunch every month to keep numbers up.

Marvel took the top spot for market share, while DC had the best-selling comic with Dark Nights: Metal #1. DC actually had the top three spots, with Secret Empire #10 coming in fourth. Image took the top spot for graphic novels with Paper Girls Volume 3.
