Today's mid-level professionals were yesterday's angst ridden youth. What does this mean? Disposable income of course. The Super Bowl panders to all things money, be it over the top ads, six hour pre-game shows and of course, the halftime blitz. It makes sense for organizers to pick a more established act with tons of fans with disposable income. After all, they want those people to tune in and watch all those beer and restaurant ads, right? Pearl Jam fits the bill nicely and fans are just still young enough to argue they can't be swayed by Madison Avenue advertising geniuses.
