Apple on Tuesday revealed its Q1 2016 earnings, announcing a huge number of iPhones sold (74.8 million), up year-over-year. All told, it meant another solid quarter for Apple, news that was highlighted by the company’s revelation that there are 1 billion active Apple devices currently on the market.

Granted, Apple surpassed one billion iOS devices sold in 2014, so the milestone is nothing new. However, this is an active install base Apple is talking about, all tied to the Cupertino company’s services, such as the App Store; as a side note, Apple said there are about 10 million paying Apple Music subscribers, so there’s still plenty of room for growth in that regard.

Despite showing strong iPhone sales, Apple has acknowledged declining sales in other categories, and expects revenue to fall between $50 billion and $53 billion next quarter. If true, it’ll mean Apple’s first quarterly drop since 2003. So far as we know, Apple will try and boost customers interest in the coming months with the release of the iPad Air 3, new Apple Watch bands, and the iPhone 5se, which will supposedly feature a 4-inch display and a design similar to the iPhone 6.

As of 2013, World Bank said there were just over 7 billion people in the world. It’s crazy to think that one billion of these people own at least one Apple product.
