According to CNNMoney.com, for the first time ever, e-book sales were higher than any other book format, both paperback and hardcover in particular. E-book sales reached $90.3 million in the month of February. Compared to the same month in 2010, that’s a 202% increase in e-book sales.

A representative from the Association of American Publishers said the data may not be perfectly reliable, but it does provide “a really good snapshot of what’s going on.” The rep. elaborated on the data saying it was given voluntarily from publishers to the AAP, and not all publishers chose to do so. Also, the AAP attributes the high sales to post-holiday, new e-reader owners.

The e-reader market consumer can now choose between Amazon’s Kindle, Borders’ Kobo, the Sony Reader, Apple’s iPad, and the Barnes & Noble Nook, all of which add to the growing e-book market.

“The book business is changing more radically now, more quickly than movies or music or newspapers have, because we’re doing it in a matter of months,” said Marc Parrish, executive at Barnes & Noble. “The next twenty four months is when this business will totally shift.”
