Betting markets in everything, Super Bowl edition

I have found odds on how long Jordin Sparks
will take to sing "The Star Spangled Banner” (wager under or
over one minute and 42 seconds) and which advertisement shown
during Super Bowl will top USA Today’s Ad Meter popularity
contest.  Budweiser is the -200 favorite (bet $200 to make $100
profit), followed by Go Daddy at +300 and Pepsi at +600.   
       

Looking through betting Web sites I have found more than
2,000 different "proposition bets,” the name bookmakers give
to markets that are about what happens around the game rather
than on the result.      

Here is the full story, and thanks to John De Palma for the pointer.  But in baseball, regulators are shutting down one nascent market.
