Superbowl XxPXXKVIII or whatever number it is

I wonder how much money is made by the NFL every year by the superbowl. I noticed that they try to get just about every demographic to watch the game by bringing in bands like the Black Eye Peas, people like Christina Aguilera, and whatever her name is from that horrible tv show glee. Im pretty confident that guys who watch a lot of football don't like those things. Pretty sure.
