Apple says there are now more than 100,000 movies and TV shows on iTunes, including a large collection of 4K HDR content that you can rent or buy. Now you can get to all that without having to leave their TV app. With channels, Apple now has the opportunity to subscribe to a number of premium networks directly from its TV application, including HBO, Showtime, Starz, Epix, Smithsonian Channel, Tastemade and later CBS All Access. While many of these services already have their own apps on Apple TV, the benefits of channels are that Apple controls the whole aspect of your experience, from how to sign up for how the content is presented visually.
In addition to that, those of you who subscribe to channels can download movies and view for offline viewing to the iPhone or iPad. HBO, for example, doesn't even offer it on the apps it does itself. According to Apple, channels subscriptions will work for up to six of your loved ones through Family Sharing so everyone can have their own watchlists. And for the young in your life, the new TV app also comes with a dedicated Kids section, which will feature movies and shows cured by Apple's editorial team.
Of course, as Apple revealed in January, the TV App will be available in 2019 Samsung's smart TVs (plus some 2018 models), along with the iTunes app and AirPlay 2 support. All you can't do To do this is to say that you have Prime Video attached to your TV app, you will not be able to pause your Apple device and then continue to watch Samsung's smart TV. Other than that, the rest of the features – channels, for you, kids and more – are all there. When it comes to Mac, don't worry, Apple is still planning to bring the TV app to notebook and desktop devices later this fall.
