WBA (World Boxing Association): Oldest organization, founded in 1921.
WBC (World Boxing Council): Founded in 1963, known for its green belt.
IBF (International Boxing Federation): Emerged from the NBA, emphasizes rankings and mandatory challengers.
WBO (World Boxing Organization): Gained legitimacy in the 1990s; now considered a major title.
