Boxing is the sweet science and the most demanding sport of all, at least according to ESPN. It is a sport that requires strength, speed, reaction, and durability to a degree unlike any other, which is why pugilism is the one original Olympic event (from those Ancient Greek times) still selling out Las Vegas arenas. Boxing tickets are still big business and its fans remain fanatics, celebrating prize fighters like Rocky Marciano, Muhammad Ali, and Manny Pacquaio and dishing out millions for the opportunity to sit ringside or watch the big fight on Pay Per View.
The most dominant organization in contemporary times is the World Boxing Organization. There are actually four major international organizations, but this is the most recognizable. Each of the four has 17 weight classes, from mini flyweight to heavyweight. The big names in the mix are Pacquaio, Juan Manuel Marquez, Floyd Mayweather, Timothy Bradley, and Wladimir Klitschko. These are the guys always on the verge of acquiring a belt or are already title holders. The smaller guys like Pacquaio, Marquez, and Mayweather throw a terrifying flurry of punches. Kitcschko is fighting fellow heavyweights, and he is the one towering above them. Boxing is still thriving and will continue to be one of the great spectacles of sport for decades into the future.
