Turns out that repetitive ads and product replacement have an inverse effect on fans.
If you've watched an NFL game or any sporting event in the past decade or so, you've probably been a victim of excessive advertising. Enslaved to their televisions, fans block off about 3 hours each Sunday for game time but only spend about 11 minutes watching game action. The rest of the game is taken up by over 20 commercial breaks, and roughly 100 different advertisements. All in all, about an hour of the game, is purely commercials. Considering all of this, it's pretty to see why watching a game from the couch is almost like an endurance sport.
