The Association of American Publishers reports February e-book sales have surpassed paperback and hard-cover book sales for the first time ever.
E-books brought in more than $90-million in February -- a 200-percent increase compared to a year ago.
The strong sales come after a holiday season in which e-readers were a big seller. The new data comes from publishers, not retailers. That means the report may not be complete, but points to an important milestone for the book industry.
