Sky's new TV platform, Sky Q, supports 4K, however the company is yet to offer any "Ultra HD" shows or movies. That should change later this year, however, and when it does, Sony's films will be some of the first that customers can watch on their pixel-dense TVs. In its press release, Sky calls out Ghostbusters, Angry Birds, Money Monster and Inferno as "major new films" that will be coming to its platform. They could be joined by many other 4K flicks, of course, including those produced by other studios.

Sky's deal with Sony is important as it tries to fight off traditional and satellite TV providers, like BT and Virgin Media, as well as streaming services like Netflix. With Sky Q and Now TV, it's trying to compete with both groups simultaneously -- and some timed exclusives, especially in 4K, could give the pair an edge in the fiercely competitive UK market.
