For all of 2011, BookStats estimated that trade publisher e-book revenues were $1.97 billion, or about 16 percent of the total trade industry . Adult fiction e-book sales more than doubled over the previous year, making up 31 percent of the category’s total.
Sales are still climbing. The January 2012 monthly StatShot reported almost $100 million in adult e-book sales, a 49.4 percent increase over the same period a year earlier. The number of self-published books produced annually in the U.S. has nearly tripled, growing 287 percent since 2006, with 235,625 print and e-titles released in 201, according to a new analysis of data from the research firm Bowker announced in October.
