From The Verge:
Propelled by DC’s Rebirth series, distributor Diamond Comics has shipped 10.26 million copies to comic book stores in North America this past August, according to industry analyst John Jackson Miller.
According to Miller, the figures for August were largely driven by DC Comics, which sold nine out of the ten bestselling issues, with Harley Quinn #1 as the top seller.
. . . .
10.26 million units is a significant figure, because the last time stores ordered in that volume was December 1996. In the following years, the industry faced some significant troubles, with its total market share dropping to $255 million in sales in 2000. Since then, it has dramatically rebounded, with an estimated $940 million in sales last year.
Vulture points to the huge number of comic book adaptations in theaters as a likely reason for the dramatic growth in sales in recent years.
