Sports fans with ESPN Classic on demand might spend the next few weeks glued to their screens. The company is giving them access to over 600 hours of archived programming. That means hundreds of hours of old basketball, football, X Games and other sports you'd usually watch on ESPN -- even "classic" ones people still talk about decades later, like Muhammad Ali's fights -- via the WatchESPN app. WatchESPN is available for a bunch of platforms, including Amazon Fire TV, Chromecast and Xbox One. But if you want to watch events you might have only heard from your parents, you'll have to bust out an Apple TV or a Roku.
