IF you had $4 million in your bank and IF all of the commercial spaces for the Super Bowl hadn't already been purchased more than 2 months before the event, you MIGHT have been able to buy a slot during the 2014 big game.

Fox sports is reporting that all the commercial spaces are sold and although they won't say for how much, top media buyers speculate the cost is around $4 million for a 30 second ad. That's $200,000 more than when CBS aired the Super Bowl in 2013.
