The Super Bowl host selection process is handled by the NFL, which votes on bids made by several candidate cities. Cities that want to host the Super Bowl have to agree to several demands from the NFL to receive serious consideration.
Cities begin to make a bid for hosting the Super Bowl three to five years before the scheduled date. The owners conduct a secret ballot over several rounds to decide which bid the league should accept. For example, the 2014 Super Bowl vote took place in 2010 when New York City and the Florida cities of Tampa and Miami made bids. The voters eliminated Miami after the second round; a majority voted for New York City after the fourth round.
For a bid to receive serious consideration, the host stadium must have a minimum of 70,000 fixed seats and 35,000 parking spaces. The NFL also reserves the right to receive all ticket sale revenue from the game. The local and state governments in the host city are expected to award tax exemptions for Super Bowl tickets. The NFL also asks that the game receive priority for emergency services, such as ice and snow removal.
If a host city experiences an average temperature below 50 degrees in February, the NFL expects the team to have a climate-controlled, domed stadium by the time the Super Bowl happens. The 2014 Super Bowl, which occurred in an open stadium in a cold-weather region, shows that a host city does not necessarily have to comply with all of the NFL's requirements to be awarded the Super Bowl.
