Video games these days often try to do a lot of things to increase immersion and make the world feel more alive. These include things like physics on various objects in the world, having characters in the background hold conversations the player can overhear, and various other tidbits of reality that are put into the game. Sometimes, it even includes a TV with actual "shows" the player can watch. But in some, especially rare, cases, the TV would display an actual "show". It might be only a few minutes long, but that's a few minutes longer than what other games show on their TVs.
