Amazon Sells More Digital Books than Paper Books

Forget digital paper: Amazon sold more electronic books on Christmas day than it did paper books, according to Information Week. Of course, that's due to the hundreds of thousands of people who unwrapped a Kindle digital reader that day and then downloaded books to the device. Still, this is quite a landmark accomplishment for digital print.

An estimated 3 million digital readers were sold this year. In 2010, that number should be around 10 million. This may not seem like a huge number vs. all the paper books out there, until you realize one device can hold over a thousand books. And the way these things go, we may be looking at a market of 100s of millions of digital readers in a few years.
