As far as media delivery goes, e-books are pretty flat. You get the book and maybe some notes or background info from the publisher, and that’s pretty much it. That’s not good enough for Amazon. The company was just awarded a patent, which it originally applied for on November 24, 2010, describing a way to enhance your electronic reading experience with more personalized content — not just from publishers, but from your friends as well. The online retailer was granted a patent today outlining a “Customized Electronic Book with Supplemental Content” (Patent #8478662). It describes a way to enhance Kindle e-books by tacking on supplemental material provided by publishers or reputable sources. The e-books would be personalized by adding additional content within the specific interests of individual readers, or reader types.
