I'm not sure why you find it so surprising. Every year 2 teams play that game in February. It's always the same: mega-hype in anticipation of the game and the commercials, and sometimes over the half-time show.
The results... everyone talks about the commercials after the game and the game is usually a sure thing (no surprises).
I haven't watched the Super Bowl in ... years. I can't even remember the last time I watched the Super Bowl, to be honest. I know it was long before I stopped watching TV altogether.
