Apple TV is a line of digital media players developed and manufactured by Apple Inc. Similarly to competing devices, they are capable of playing media content streamed from online services (including Apple TV, Apple Music, iTunes Store, and other third-party platforms), compatible devices over a local network (including protocols such as AirPlay), and stored on the device's internal storage. Since 2015, Apple TV devices run tvOS, an operating system derived from iOS that uses a 10-foot user interface optimized for televisions. They can also serve as a home hub for the Apple Home smart home platform.
The first generation Apple TV was introduced in 2007; it was primarily designed to download and play content from iTunes Store, synchronized from a Macintosh or PC, while a software update in 2008 added support for accessing content directly from Internet services such as iTunes Store and MobileMe, without the need for it to be synchronized from a computer. The second-generation Apple TV was released in 2010, which switched from Intel processors to Apple A-series chips, and introduced a new operating system derived from iOS. With the release of the fourth-generation model in 2015, the system software was renamed tvOS, and began to support third-party software via an app store, and integration with Siri.
