Apple, from their press release:
Apple today announced that the App Store welcomed 2017 with its busiest single day ever on New Year’s Day, capping a record-breaking holiday season and a year of unprecedented developer earnings and breakout app hits. In 2016 alone, developers earned over $20 billion, up over 40 percent from 2015. Since the App Store launched in 2008, developers have earned over $60 billion, creating amazing app experiences for App Store customers across iPhone, iPad, Apple Watch, Apple TV and Mac. Those efforts helped kick off 2017 with a remarkable start, making New Year’s Day the highest single day ever for the App Store with nearly $240 million in purchases.
“2016 was a record-shattering year for the App Store, generating $20 billion for developers, and 2017 is off to a great start with January 1 as the single biggest day ever on the App Store,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing. “We want to thank our entire developer community for the many innovative apps they have created — which together with our products — help to truly enrich people’s lives.”
Customers broke all-time records this holiday season with purchases from the App Store topping $3 billion in December. In the same month, Nintendo’s Super Mario Run made history with more than 40 million downloads in just four days after its release, and was the most downloaded app globally on Christmas and New Year’s Day.
Amazing sales numbers.
