In the two year period between April 1, 2010 and May 21, 2012, 1.3 million individual titles have been purchased and that Amazon, BN, Apple and Sony account for 98% of all retail ebook sales. That leaves 2% to divide between Kobo, Smashwords, All Romance eBooks, and the like.
I’m not sure I agree with McIlroy’s final conclusion – that ebooks are having a significant role in reducing industry dominance by the largest publishers. He states that in 2004, the top 5 held 65.1% of the market. That large publishers supply only 8% of the ebook titles and achieve 50% of ebook sales doesn’t mean that their market dominance is declining, only that it has achieved 50% of the ebook market. What is their percentage of the print market? Is it lower than 65.1%? Higher? Looking at the publisher position in the marketplace without considering print component is looking at only half the picture and lends itself to faulty conclusions. Thad McIlroy – Future Of Publishing
