When the Apple TV 2nd generation was introduced in 2010, it received support for the AirTunes protocol. However, because this device allowed playback of visual content, the protocol was extended and renamed AirPlay. It was now possible to stream photo slideshows and videos. Shortly after the release of the Apple TV 2nd generation, AirPlay support for iOS was included in the iOS 4.2 update. It seems like at that point, the audio stream was still actually using the same AirTunes 2 protocol as described above. The video and photo streams were added as a whole new protocol based on HTTP, pretty much independent from the audio stream. Soon, the first curious developers began to [investigate how it worked](https://web.archive.org/web/20101211213705/http://www.tuaw.com/2010/12/08/dear-aunt-tuaw-can-i-airplay-to-my-mac/). Their conclusion was that visual content is streamed unencrypted.
In April 2011, a talented hacker [extracted the AirPlay private key](http://www.macrumors.com/2011/04/11/apple-airplay-private-key-exposed-opening-door-to-airport-express-emulators/) from an AirPort Express. This meant that finally, third-party developers were able to also build AirPlay reveiver (server) programs.

For iOS 5, released in 2011, Apple added a new protocol to the AirPlay suite: AirPlay mirroring. [Initial investigators](https://www.aorensoftware.com/blog/2011/08/20/exploring-airplay-mirroring-internals/) found this new protocol used encryption in order to protect the transferred video data.
