The online retailer began selling electronic books for its Kindle in 2007. Since April 1, 2011, it has sold 105 Kindle books for every 100 print books, hardcover and paperback. And that figure excludes free Kindle books.
Digital books have clearly come into their own. Amazon also said it has sold three times as many books on the Kindle so far this year as it did in the same period last year.
Have you replaced the book in your purse or briefcase with an eReader? Or are you loath to give up the feeling of turning pages?
