Growth market

The Pew Internet and American Life Project just released a "mini-report" on the recent upswing in e-reader purchase and usage. According to the report, the number of Americans owning tablets and e-readers nearly doubled over the past month: from mid-December 2011 to early January 2012, the number of Americans owning a tablet computer and the number of people who identify themselves as e-book readers jumped from 10% to 19%.

Clearly, all those dead-cheap e-reader promotions over the holidays worked.
