The International Boxing Organization (IBO) is a for-profit organization that sanctions professional boxing matches and awards world and regional championships.
The IBO was founded in 1988 and incorporated in Illinois in 1992 by John W. Daddono. The organization was later moved to Florida in 1996 and incorporated in Florida at that time. Ed Levine, who continues to serve as the organization's President became a partner and President of the IBO in 1999.
The organization received acclaim by implementing a computerized system in the late 1990s that removed subjective elements from the ratings in an effort to bring more credibility to the sport. Many marquee champions have held and continue to hold the International Boxing Organization World title.
