The league announced on October 16, 2012, that the two finalists were Sun Life Stadium and Levi's Stadium. The South Florida/Miami area has previously hosted the event 10 times (tied for most with New Orleans), with the most recent one being Super Bowl XLIV in 2010. The San Francisco Bay Area last hosted in 1985 (Super Bowl XIX), held at Stanford Stadium in Stanford, California, won by the home team 49ers. The Miami bid depended on whether the stadium underwent renovations. However, on May 3, 2013, the Florida legislature refused to approve the funding plan to pay for the renovations, dealing a significant blow to Miami's chances.
