Estimated Overall Sales of Comic Books, Trade Paperbacks, and Magazines from Diamond Comic Distributors to Comics Shops in North America

Diamond Comic Distributors,
the sales agent for most North American comics publishers serving the
comics shop "direct market," reports monthly market shares for its
sales of comic books, trade paperbacks, and magazines Using those
ratios and publisher information detailing the exact amounts Diamond
sold, the Comics Chronicles projects the above overall sales for
each month since January 2003.
As the calculation includes non-comics magazines, the true figure is slightly lower each month.
The above figures include several important components. Much of the comics industry's sales come from comic books in periodical form.
Beginning in the 1980s, comic book distributors Capital City Distribution and, later, Diamond, began reporting indexed unit sales for the comic books they sold. While the distributors did not make the actual sales figures public, publishers often provided analysts with issue counts ordered by those distributors, thus unlocking the entire sales chart. Beginning in September 1996, I began producing estimates based on Diamond's indexed sales; for the period up until April 1997, I also included actual sales of Heroes World Distribution, which had for a time served as Marvel's sole distributor.
