Apple’s iBooks Numbers

According to Apple’s chief executive—Steven P. Jobs, it is announced on Monday at Apple’s Worldwide Developers Conference that the sales of e-books for the iPad has now accounted for 22% of all e-book sales.
The number of 22% means little as it does not reflect the entire publishing industry. Most small publishers, as well as one of the largest in the world—Random House, do not sell books via Apple. However, though Amazon.com can pretty much dismiss the number as overstated, its executives still have good reason to be concerned about the threat Apple poses to the Kindle.
