Leading TV manufacturers are integrating AirPlay 2 directly into their TVs, so now you can effortlessly share or mirror almost anything from your iOS device or Mac directly to your AirPlay 2—enabled smart TV. You can even play music on the TV and sync it with other AirPlay 2—compatible speakers anywhere in your home.

So far, Samsung, Vizio, and LG have announced plans to work with AirPlay 2.

…what does this mean for the Apple TV?
