Here’s how quickly Amazon’s Kindle ecosystem has grown, via Jeff Bezos’ presentation this morning. Note the acceleration as the Kindle has gotten cheaper and as Kindle apps have become widespread.

Also interesting: How physical book sales dropped after the dot-com bust, but not during the most recent recession. And how physical book sales are still growing — faster, even — despite the Kindle.
