Amazon's Kindle wasn't the first e-reader on the market, but it's continuing the Amazon tradition of shattering sales paradigms – Amazon announced today that it now sells more Kindle e-books than traditional print books.
Amazon reports that since April 1st, the company has sold 105 e-books for every 100 print books. That's not including all the free downloads of public domain books, either. It's not surprising when you consider just how ubiquitous the Kindle's become in just four years – even if you don't have an actual Kindle, you can read Kindle books using the Kindle app that's available for many mobile devices.
