These superheroes will still save the day, but in digital format. DC Comics said Wednesday its full lineup of comic books will be made available for tablet computers from three powerhouses of digital distribution -- Amazon's Kindle Store, the Nook Store from Barnes & Noble and the iBookstore for Apple devices. That means Batman, Superman, Wonder Woman and the Justice League comics will be offered in digital format for tablets and e-readers. "As e-readers and tablets continue to explode in popularity, it's important for us to offer consumers convenience and choice in how they download digital comics and graphic novels and these new distribution deals with the top three e-bookstores do just that," said Jim Lee, co-publisher at DC Entertainment. "We're very excited to work with Amazon, Apple and Barnes & Noble to bring best-selling DC Comics and Vertigo periodicals to their e-bookstores." DC Entertainment said it is the only comic book publisher to offer its periodical line-up across all major e-bookstore platforms. Prior to the announcement, only DC Entertainment graphic novels were available through the top e-bookstores. But the comics may also be downloaded directly from the company website. "We were the first to offer our entire comic book line same-day digital and now we are the first to offer fans the convenience of multiple download options," Lee said.
