Playing YouTube on Apple TV.

Hi. If you have Apple TV 4 (the current model) you can download the YouTube app from the TV app store on the Apple TV. Earlier models should already have it; check the full list of channels in case it is hidden. You can also use AirPlay from an iOS device, using the YouTube app or browser on the device.

if you have an appletv 2g or 1g you will not be able to though because google changed the api so the build in app don't work anymore, in case of the 2g you should still be able to airplay youtube stuff from an iOS device though
