CES and Apple don’t usually go together, but anything goes so far in 2019. Apple announced that it will bring AirPlay 2 and HomeKit compatibility to several televisions in 2019, spanning models from manufacturers like Samsung (its new TVs will have iTunes built in, though they will lack HomeKit support) LG, Sony, and Vizio. Not in the market for a new TV? If you bought your television within the past year or two, there’s a slim chance that it could get AirPlay 2.
Beyond making it easy for iPhone, iPad, and macOS users to push content to their televisions, AirPlay 2 allows for multiroom audio. So with the feature built into future TVs (or patched into one that might already be in your home), your TV can easily connect to other AirPlay 2-compatible devices, like Sonos speakers and the Apple HomePod.
