AirPlay

AirPlay (formerly AirTunes) is a Bluetooth-enabled feature developed by Apple Inc. It uses wireless streaming to broadcast media from an iPhone, iPad or Mac to other Apple devices, such as an Apple TV, with the option to play the audio through a HomePod or HomePod mini.

History

Airplay screen mirroring was introduced with iOS 5, which was released on October 12, 2011. AirPlay 2 was introduced with iOS 11.4 on May 29, 2018, adding support for control of home audio systems.
