The figures, which were posted on GalleyCat on Friday, show that net sales revenue from ebooks exceeded that of hardcover books in the first quarter of the year: a first. The data was compiled from 1,189 publishers and did not include children’s books.
Collectively, adult ebooks brought in $282.3 million in Q1. That’s an impressive 28.4% increase from the same period a year ago. Young adult and children’s ebooks performed even better, catapulting 233% to $64.3 million. Sales of adult hardcover books grew too, but more modestly, up 2.7% to $229.6 million in Q1 2012."
