The United Center is home to both the Chicago Blackhawks of the NHL and the Chicago Bulls of the NBA. The United Center seats 20,500 for hockey, 22,879 for basketball and up to 23,500 for concerts, and hosts over 200 events per year, drawing over 20 million visitors since its grand opening. The United Center was also the site of the WWF SummerSlam in 1994, and the 1996 Democratic National Convention. The arena claims to be the largest in the United States - in physical size, not in capacity. The privately-owned arena is 960,000 square feet big and is located on a 46 acre parcel west of the Chicago Loop.
