Amazon already owns the most popular brand for ebooks, having debuted the Kindle ages ago and attracted consumers and publishers alike before other big players managed to establish a foothold in the industry. Now the company's going after comics. It could continue to expand its library of Kindle editions, but the speedier approach would be the buy the best competitor out there. So that's what Amazon is doing. The company has just announced plans to acquire comiXology, the makers of a popular digital comics platform, not to mention a couple of great Android comic book reading apps.
A large amount of that comics market has been claimed to the app ComiXology; it's usually been the gold standard for a lot of comic-dom's digital offerings. However, as with other things, it's almost impossible to enforce a standard.
DC Comics has partnered with ComiXology in order to produce their own digital offerings, and distribute them to their audiences. This app uses a lot of the same technologies as ComiXology's, like the Guided View, which allows for easy touch-based scrolling.
