As noted by TechHive, comiXology is already one day into its summertime promotion, but new and existing users can still take advantage of 19 free comics to be released in as many days.
The first comic, DC #871 "Batman -- The Black Mirror Part 1, was released on Monday, while today's freebie is a special digital edition of Gold Key's "Magnus: Robot Fighter." The company will continue to announce new titles through June 14, when the promotion is scheduled to end.
ComiXology ruffled some feathers in April when it discontinued its longtime Comics iOS app, which effectively removed in-app purchasing from the title. Instead of paying Apple's usual 30 percent commission fee, parent company Amazon released a new version of the app that forces users to make purchases through Safari.
At the time, the comiXology offered existing account holders a $5 gift card to switch over to the new app, which was last updated on May 6.
Monday's summer promotion is the latest bid from comiXology to gain a fresh user base after Amazon bought the company in April. It was speculated that Comics' unique "Guided View" technology for reading made-for-print comics would be integrated into Amazon's Kindle ecosystem.
Alongside its proprietary comic reading tech, ComiXology is responsible for digital copies of content from a wide range of publishers including Marvel and DC Comics. In addition, the company holds exclusive iOS content rights to major titles like "The Walking Dead."
