In a momentary break from all the CES madness, Apple has revealed some 2013 sales figures from its App Store. And the results are staggering.

Customers spent more than $10 billion on the App Store last year, spending over $1 billion in December alone. In fact, customers downloaded almost 3 billion apps in December. Presumably, Apple gift cards were huge for stocking stuffers, helping to make December the most successful month in App Store history.

Eddy Cue, Apple's senior vice-president of nternet software and services, gave credit to a line-up of "astonishing" apps during the holiday season, including "surprise hits" as Moves Afterlight. Some of 2013's biggest successes include Candy Crush Saga and Puzzles & Dragons.
