It would be fun to think about predictive upcoming down/ad time. For example, one of the worst offenders in live sports is the ad break-kickoff-ad break sequence in an NFL game. If you could predict based on how many ad breaks have already happened whether such a thing was about to take place, you could get buzzed right after a touchdown: "hey, you're about to get 6 minutes where nothing happens but a touchback, you can take a bathroom break plus refill your drink."
