The International Boxing Organization (IBO) is a business located in the United States that sanctioned professional boxing events and awarded world and regional championships.
It is a well-known independent organization that is not recognized by the “big four” regulatory bodies (WBA, WBC, IBF, and WBO), which only acknowledge each other in their rankings and championship unification regulations.

John W. Daddono started the IBO in 1988 and incorporated it in Illinois in 1992. The group was later relocated to Florida in 1997 and incorporated there. At the time, Ed Levine, who is now the organization’s President, became a partner and President of the IBO.
In the late 1990s, the organization garnered accolades for establishing a computerized method called ‘The Independent World Boxing Rankings,’ which eliminated subjective factors from the ratings in an effort to give the sport more respect.
