A couple of major (Big Six) publishers have acknowledged that ebook revenues for them have passed 20% of their revenues. Of the 80% that remains print, I think it would be conservative to estimate that 20% of that is sold online. That’s an additional 16 percent of their business. Adding those together tells us that, for at least some very major companies, 36 percent of of their sales are being transacted online. That would leave, on average, about 64% of the sales for print sold through brick-and-mortar retail and other more minor channels. ”On average” should not be read as “typical” on a title-by-title basis. It isn’t. For immersive reading, or straight text like novels and biographies, the percentage sold in stores is already almost certainly substantially lower. My hunch, and nobody really keeps these figures (but I think I’ve found a way to get at them, which we’ll try to show at a future Publishers Launch conference) is that it may already be down to 50% print in stores for new titles.
