The market for what is now referred to broadly as “graphic novels” has grown strongly since 2000. Many factors contribute to this growth including such things as an explosive growth in the number of unique book titles published annually, the success of super hero movies, and a growing influence from the comic arts scenes in other countries where it has been a strong cultural outlet. In terms of revenue produced by the sales of these graphic products, market share breaks down by category as follows: comic periodicals, 27.5%; Manga, 12.4%, and other graphic novels, 60.2%.
