Trade publishing revenues from ebooks increased 5.1% to $404.8 million in the first quarter of 2014, according to the latest figures from the Association of American Publishers.
Hardcover and paperback formats grew even faster, however, in the first quarter: hardcover revenues rose 9.8% to $492 million; and paperbacks grew 5.3% to $458 million.
Gains across the board were driven by children’s and young adult ebooks, which got a boost from the early-year successes of Veronica Roth’s Divergent trilogy and John Green’s The Fault in Our Stars. The two books combined for almost the entire first quarter’s No. 1 ebook best-seller rankings. The Fault in Our Stars has since been No. 1 on the ebook best-seller list for ten straight weeks.
Across print and ebooks, young adult books rose 31.5% to $411 million for the quarter. Adult books and religious books were basically flat for the quarter.
