When it was built, it was the largest indoor arena in the world with a maximum seating capacity of 26,000. It was the home of the National Hockey League's Chicago Blackhawks and the National Basketball Association's Chicago Bulls. It was used for numerous other sporting events, opening with a championship boxing match in March 1929. The Stadium was built by Paddy Harmon, a promoter, who sank his entire fortune into the project, only to lose control to the Stadium shareholders. After exiting receivership in 1935, the Stadium was owned by the Norris and Wirtz families until its closure in 1994. It was replaced by the United Center built across the street, also owned in part by the Wirtz family.
