Amazon is reporting:
During the past 30 days, Amazon.com customers purchased more Kindle books than print books--hardcover and paperback combined--for the top 10, 25, 100, and 1,000 bestselling books on Amazon.com.
For the top 10 bestselling books on Amazon.com, customers are choosing Kindle books over hardcover and paperback books combined at a rate of greater than 2 to 1.
I'm not sure how they figure "best-selling". Does it count both e-books and print books? Is it based on unit sales, wholesale price, selling price, or list price? The "more sales" is pretty clearly on unit volume.
Regardless, that sounds like a pretty big milestone for e-books.
That's good news for all of us authors. The book prices for Nook and other mobile readers are usually lower than for print books, which may account for some of the statistics.
Personally, I sell more copies of my novel here at B&N, but maybe it's because Amazon has a larger selection.
Thanks for the info. Pam
