University of Phoenix Stadium
The 63,500-seat home of the Arizona Cardinals has been named the University of Phoenix Stadium. This is the first time a National Football League venue has been named after an educational institution.

The stadium features the first fully retractable natural grass playing surface built in the United States on top of an AirField Systems synthetic drainage system. An opening on one side of the stadium allows the playing field to move to the exterior of the building, allowing the entire natural turf playing surface to be exposed to daylight when it is not in use and also allowing the floor to be used for other purposes without damaging the playing surface.
The University of Phoenix, a for-profit university specializing in adult education, acquired the naming rights in September 2006, shortly after the stadium had opened under the name Cardinals Stadium. The "University of Phoenix" name is applied as a corporate sponsor, and not as the home stadium of the University (which has no intercollegiate athletics program).
