Amazon provides stats on mobile use, Prime, e-books, Appstore

|By:, SA News Editor

Amazon (AMZN +0.3%), which has been infamously secretive over the years when it comes to sharing business details, has provided a handful of interesting stats in a PR discussing the company's holiday season and full-year performance.

Some noteworthy figures: 1) Over half of all Amazon shoppers used a mobile device during the holiday season. 2) 1M+ Prime subs were added during the third week of December, and there are now "tens of millions" of subs altogether. 3) 200K+ "exclusive" books were added to the Kindle store in 2013, and 150 authors sold 100K+ copies of their books via Kindle Direct Publishing. 4) The number of apps in Amazon's Appstore for Android more than doubled in 2013, and is now above 100K (still well below Google Play).

Research firm CIRP recently estimated Amazon had 16.7M Prime subs, up 72% Y/Y. The company's October decision to hike its free shipping minimum to $35 may have led to a pickup in subscriptions.

Shares are edging higher on a day that has also seen ChannelAdvisor provide favorable sales data for its clients' Amazon sales. Rival eBay, by contrast, is selling off.
