DC Comics narrowed Marvel Comics' market share lead in Q4 2021, based on sales of comics and graphic novels tracked at point-of-sale by the ComicHub system at stores selling American comics around the world, and provided to ICv2.  DC closed to within five share points of Marvel, a big improvement over the 8.1% spread in Q3 (see "Comic Store Publisher Market Shares – Q3 2021").  Their combined share was about the same as in the previous quarter.

Image Comics’ share declined 1.5% to 11.5%, from 13% in Q3 and a recent high of 15.4% in Q2.  Shifts by other publishers were all less than 1%, while BOOM! Studios' share hit a new high of 6.0%.  For the second quarter in a row, two manga publishers made the top ten publishers in comic stores, a reflection of the category's strength even in the cultural home of superheroes.

The data on which these market share percentages are based is from sales tracked at point-of-sale by the ComicHub system at stores selling American graphic novels around the world.  During the period for which these reports were generated, there were over 100 stores using the ComicHub system.  As this is a small, non-random sample of over 3,000 stores selling American comics worldwide, these rankings may not be typical for all stores, but do represent a variety of locations and store emphases.

The differences in how the data behind these charts is collected compared to past market share charts based on sales by Diamond Comic Distributors to comic stores are many.  Here are some:

Sell-in charts show all the launch sales happening on the same day, while sell-through sales happen over time, moving sales into different periods.

Sell-in shows what retailers think they will sell, while sell-through shows what they actually do sell.

Sell-in sales are influenced by incentive variants, which increase the number of copies ordered (to get a variant that can be sold at a premium price), but may not increase the number of copies sold at retail by the same amount.
