Apps have liberated television, letting you choose precisely what and when you want to watch. Apps like Hulu, Netflix, HBO Now, Watch ESPN, and iTunes give you access to everything that entertains you — from blockbuster movies, TV shows, and live sports to breaking news and weather. There are also shows for kids, music events, live feeds and podcasts.
Apple TV is also hub for Apple HomeKit to automate and remotely control your HomeKit accessories from your iOS device. Apple TV (4gen) supports high definition videos at 1080p but not 4K.
