tvOS (formerly Apple TV Software) is an operating system developed by Apple Inc. for the Apple TV, a digital media player. In the first-generation Apple TV, Apple TV Software was based on Mac OS X.[3] Starting with the second generation, the software is based on the iOS operating system and has many similar frameworks, technologies, and concepts.
The second- and third-generation Apple TV have several built-in applications, but do not support third-party applications.
On September 9, 2015, Apple announced the fourth-generation Apple TV, with support for third-party applications. Apple also changed the name of the Apple TV operating system to tvOS, adopting the camel casenomenclature that they were using for their other operating systems, iOS and watchOS.[4]
