The United Center is an indoor sports arena located in the Near West Side community area of Chicago. It is named after its corporate sponsor, United Airlines. The United Center is home to both the Chicago Blackhawks of the National Hockey League and the Chicago Bulls of the National Basketball Association . The plan to build the arena was created by Bill Wirtz and Jerry Reinsdorf, the owners of the two sports teams, respectively. The United Center's predecessor was the indoor Chicago Stadium, the original "Madhouse on Madison", which was demolished after the newer arena opened for business on August 18, 1994. A statue of Michael Jordan is located on the east side of the arena. United Airlines pays about $1.8 million per year until 2014 for its naming rights.
The United Center, which is currently owned by Rocky Wirtz and Reinsdorf, covers 960,000 square feet (89,187 m²) and is located on a 46-acre (19 ha) parcel, west of the Chicago Loop. The arena claims to be the largest in the United States in physical size, though not in capacity. Its exterior bears a striking resemblance to that of Chicago Stadium. It seats 19,717 (not including standing room) for hockey, 20,917 for basketball and up to 23,500 for concerts. The United Center hosts over 200 events per year and has drawn over 20 million visitors since its opening. It is known for routinely meeting or exceeding seating capacity for Bulls and, as of 2008, Blackhawks games.
United Center's acoustics were designed to amplify the noise level in order to recreate "The Roar" – the din of noise that made Chicago Stadium famous, especially during hockey games. During hockey season, an Allen Organ that is a replica of the old arena's famous Barton organ is used; recreating the old organ's notes took two years.
