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
AirTunes was launched in June 2004 for the streaming of audio. It was renamed AirPlay on September 1, 2010 to reflect the ability to stream video to the screen of another device. The iOS version was released on November 22, 2010, and screen mirroring was introduced in June 2011. AirPlay can be used from a PC by installing iTunes for Windows, or other 3rd party software.
