In a press release published yesterday, Apple Inc. announced that a record-breaking $10 billion had been spent at the App Store in 2013, with over $1 billion of it coming from December 2013 on nearly three billion apps.
"We'd like to thank our customers for making 2013 the best year ever for the App Store," said Eddy Cue, Apple's senior vice president of Internet Software and Services. "The lineup of apps for the holiday season was astonishing and we look forward to seeing what developers create in 2014."
The company puts it down to the introduction of iOS 7, which allowed developers to reimagine apps and base them on the newly redesigned user experience. Successes this year included apps like Candy Crush Saga, Duolingo, Puzzles and Dragons and Minecraft, which Apple noted came from developers from all over the world, and not jsut the US.
Nowadays, the App Store offers more than one million apps to Apple devices in 155 countries around the world, with more than 500,00 native iPad apps available.
