NEW YORK — Amazon.com Inc. said yesterday that, after less than four years of selling electronic books, it’s now selling more of them than printed books.
The online retailer said that since April 1, it has sold 105 e-books for every 100 printed books, including printed books for which there is no electronic edition. The comparison excludes free e-books, which would tip the scales further if they were included.
Printed books include both hardcovers and paperbacks. In July, Amazon said that e-book sales had outstripped hardcover sales. It’s now selling three times as many e-books as it did a year ago.
