International Boxing Club
The International Boxing Club was formed by Jim Norris, Arthur Wirtz, and Joe Louis in 1949, with Norris taking 80% of the stock. Norris also served as the IBC's President. The IBC was set up in direct opposition to Mike Jacobs' Twentieth Century Sporting Club. 
Norris was a very unsavory individual and was widely known to associate with criminals. As president of the International Boxing Club, Norris had a monopoly on championship fights due to a lucrative contract the IBC had to broadcast fights on national television.
Norris was responsible for fixing numerous bouts. Besides match fixing, he was also unofficially managing many boxers (usually against their will) and persuading them to hire his associates as advisers.
