context: During the first half of the 20th century, the focus of professional boxing shifted from Britain to the United States. Although there were no official world championships, the names listed in The National Police Gazette were generally considered world champions. In the 1920s, the NBA (National Boxing Association) began hosting the World Cup. At the same time, Ring Magazine was established to publish the Champions lists. In 1962 the NBA changed its name to WBA (World Boxing Association), and the following year it received its first competitor, WBC (World Boxing Council). Neither of them was generally recognized and this led to differences in world championships, among other things. In addition, a new organization, the International Boxing Federation (IBF), was established in 1983 and has its own world championships in each weight class. In 1988, another fourth world-wide WBO (World Boxing Organization) was formed when a group of Puerto Rican and Dominican businessmen argued with the WBA. In addition to these four big ones, there are countless other organizations that share their World Championship titles, but because of their small size, they are not generally recognized among the four largest federations.
