Apple's App Store had a record-breaking period this past holiday season. In the two weeks ending January 3, customers spent over $1.1 billion (USD) on apps and in-app purchases, setting back-to-back weekly records for traffic and purchases. January 1, 2016 marked the biggest day in App Store history with customers spending over $144 million (USD). It broke the previous single-day record set just a week earlier on Christmas Day.
Possibly an indicator of new iPhones and iPads sold over the holidays with new owners downloading apps (we'll know more on Apple's earnings call on January 26), this latest news reflects Apple's lead in developer communities and app ecosystems.
