Last July we reported that Amazon’s Kindle eReader books had surpassed hardcover books sales, selling 143 Kindle books for every 100 hardcover books. Now the same is true of paperbacks as well with 115 Kindle books being sold for every hundred paperbacks.
The hardcover stats for books have doubled, with three times as many Kindle books as sold as paperbacks in 2010. Free Kindle books are not part of this number.
The Kindle store now has over 810K books most of them are $9.99 or less. Amazon had its first ever $10 billion quarter. Amazon CEO Jeff Bezos predicted this digital to print milestone would happen in the second quarter of this year, so it has come ahead of expectations..
