Hachette, one of the “big five” publishers, reported that ebooks accounted for 7.9% of its global revenue in 2018:
Hachette reported that sales of digital audio rose 30% across its publishing operations and accounted for 2.7% of total revenue, up from 2.0% a year ago. Ebook sales fell in the United States and United Kingdom, but still represented 7.9% of revenue.
One would imagine that the other publishers experienced similar numbers.
Granted, 7.9% is not nothing, but it falls short of expectations..and previous hype. A few years ago, all the pundits were predicting the end of paper, and the triumph of the ebook…So far that hasn’t happened.
I see similar results in my own books. Since I released the paperback edition earlier this year, 12 Hours of Halloween has been selling almost as many copies in paperback as it does in Kindle.
