E-books are now the #1 selling format in the U.S. And that’s not just in terms of volume, but in dollars too. The Association of American Publishers (AAP) yesterday released sales figures for the month of February, and I was blown away. E-book sales (year on year) grew over 200%. They now comprise 29.5% of the market. And this is only e-book data from 16 of the biggest publishers reporting versus 84 publishers reporting print data, the real number could be higher. But the headline news was this: e-books are the top-selling format across all trade categories. More than paperback!
