Question: who decides where the super bowl is played?
Answer: the NFL, The NFL owners, NFL owners

The location of the Super Bowl is chosen by the NFL well in advance, usually three to five years before the game. Cities place bids to host a Super Bowl and are evaluated in terms of stadium renovation and their ability to host. In 2014, a document listing the specific requirements of Super Bowl hosts was leaked, giving a clear list of what was required for a Super Bowl host. Much of the cost of the Super Bowl is to be assumed by the host community, although some costs are enumerated within the requirements to be assumed by the NFL.
