Amazon has sold “millions” of third-generation Kindle electronic readers in the most recent quarter.
Amazon.com (AMZN) is now selling more Kindle e-books than paperbacks, the world’s biggest online retailer reported. But Amazon’s fourth-quarter financial results were mixed. Amazon says net income for the quarter climbed 8%, which surpasses Wall Street expectations. But revenue fell short, sending shares down nearly 10% at one point in extended trading.
