@izzythepush,
I can only really compare NFL games against each other. It certainly felt like the super bowl had more breaks than eg the divisional playoff games. In fact there were a few times during the super bowl where the network didn't even go to break between drives – a good indicator of a slog game.
Most of the time though I'll record a game I want to watch, then start watching an hour later so I can fast-forward through most of the commercials, so I might not actually be the best judge here.
I also enjoy watching the NHL playoffs, and the stretches between commercials are noticably longer than NFL games.
