From Mike Shatzkin on The Shatzkin Files (The expected changes in the book business favor Amazon’s share growth):
My own expectation is that over the next five years we’ll see the share of sales that are ebooks more than double. (This should be seen as a startlingly conservative prediction, since that number has doubled annually for the past five years!) That would put ebook unit sales at about 65% for commercial immersive reading. (I’m grossing up the 20% of revenue number the big houses are reporting because ebooks produce less revenue than print hardcovers and because many titles in the print revenue base aren’t in the ebook revenue base.)
Of the remaining 35% allocated to print, I’d expect half of the sales, at least, to be online. If those numbers are right, then 17.5% of immersive book sales would be in brick stores.
