Amazon: E-Books Outsell Actual Books Amazon sells 105 e-books for every 100 printed books By Newser Editors and Wire Services Posted May 19, 2011 12:20 PM CDT Updated May 19, 2011 5:53 PM CDT 6 comments Comments This product photo provided by amazon.com Inc., shows the Kindle 3 reader. (AP Photo/amazon.com Inc.) (Newser) – It took e-books less than four years to achieve world domination—or, at least, Amazon.com domination. Amazon now officially sells more electronic books than printed books. Since April 1, it has sold 105 e-books for every 100 printed books. What's behind those numbers? Printed books include both hardcover and paperback versions, as well as printed books for which there is no electronic version; the comparison excludes free e-books.
