[12] In April 2014, Amazon acquired ComiXology for an undisclosed sum, which The Motley Fool argued was an attempt to control the comic book market after Amazon Publishing's Jet City Comics imprint failed to achieve major market share after its July 2013 launch.

[13][14] In May 2016, the company launched ComiXology Unlimited, a subscription service that gives digital access to thousands of comics to read from most major publishers for a monthly fee of $5.99.

ComiXology Unlimited contains a selection of titles from Image Comics, Dark Horse, IDW Publishing, BOOM!

On April 9, 2013, writer Brian K. Vaughan issued a statement[40] on Fiona Staples's blog that Apple Inc. had prohibited the sale of Saga #12 through iOS.

This statement was quickly reported by the media, the impetus for the "ban" was speculated to be in response to two panels that depicted oral sex between men in a small, inset image violated Apple's restrictions on sexual content.

The ban was criticized by artists and writers, who pointed to similarly explicit content in previous issues and in other works sold through iTunes.

William Gibson and others suggested that the restriction could have occurred specifically because the drawings at issue involved gay sex.

This change resulted in immediate internet backlash from the comic book reader community, criticizing Amazon's acquisition of the distributor.
