Xbox 360 in the tail years (post 2010) and Xbox One from the get go, have good feature addressing TV, content and apps. Actually, XB1 is perhaps the only device that you can feed live TV from antenna or cable through it.
Xbox One was supposed to be the culmination of the vision. Too bad Microsoft alienated their audience (gamers), by mixing messages and designing their whole interface around a hardware fad, the Kinnect. Didn't help that they also alienated so many independent developers and which left them with a dearth of software as well.
