Apple has announced that its active installed base of devices has reached 1 billion, based on the number of iPhone, iPad, Mac, iPod touch, Apple TV and Apple Watch devices that have been engaged with the company's services within the past 90 days. Apple said the figure represents a 25% year-over-year increase in active devices.
Apple sold a record 74.8 million iPhones, along with 5.3 million Macs and 16.1 million iPads during the first quarter of the 2016 fiscal year. Apple also earned slightly over $6 billion in revenue from services, including App Store and iTunes sales, AppleCare, Apple Music subscriptions, Apple Pay, licensing and more.
Earlier this month, Apple said the 2015 holiday season was the "biggest ever" for the App Store, with customers spending a record-breaking $1.1 billion on apps and in-app purchases over a two-week period ending January 3. New Year's Day set a single-day record with $144 million in sales, just one week after setting a Christmas Day sales record.
Apple's latest data shows that iOS 9 is installed on 75% of active iOS devices, as measured by the App Store on January 11. 19% of devices are still running iOS 8, while the remaining 7% of devices are using an earlier iOS version. Apple previously said iOS 9 is on pace to be downloaded by more users than any other software release in the company's history.
