Apple builds consumer technology around a tightly integrated ecosystem of hardware, software and services. The company designs the iPhone, Mac, iPad, Apple Watch and AirPods, along with the chips inside them and the operating systems they run. A growing share of its business comes from services such as the App Store, iCloud, Apple Music and Apple Pay, which monetize an installed base of well over a billion active devices. Founded in 1976, Apple is known for premium pricing, deep vertical integration and one of the most loyal customer bases in consumer electronics.
