Of all the books that Amazon sells, what percentage are digital books?
[Bezos:] For every 100 copies of a physical book we sell, where we have the Kindle edition, we will sell 48 copies of the Kindle edition. It won’t be too long before we’re selling more electronic books than we are physical books. It’s astonishing.
How quickly are paper books migrating into their digital equivalents?
[Bezos:] When we launched Kindle two years ago, it was 90,000 titles, and today it’s more than 350,000. We’re adding thousands of titles every week. Our vision is every book ever printed in every language, all available within 60 seconds.
