What you see from my chart is that ebook sales grew nicely between 2002 and 2007, but were really too small to register on the radar screens of most industry watchers. Starting in 2008, however, the growth rate started to accelerate, and then this acceleration continued throughout 2009 and into the first month of 2010.
According to the AAP, in 2009 ebooks accounted for 3.31% of all trade book sales, up from only 1.19% in 2008. Even if sales stay flat from January onward in 2010, we’re looking at ebooks accounting for 6-8% of U.S. book sales in 2010. If sales accelerate further, a 10% monthly run rate is certainly likely by the end of this year. These numbers are dramatically higher than most reasonably-minded industry watchers predicted even a few months ago.
