Boxing in the 1980s was filled with important fights, events and personalities that shaped the sport. Boxing in the 1980s was shaped by many different situations, such as the continuous corporate battles between the different world sanctioning organizations, the void left by Muhammad Ali as the sport's ambassador and consequent search for a new boxing hero, the continuous presence of Don King as the sport's most famous promoter, the surge of rival promoters as Bob Arum, Butch Lewis and Murad Muhammad, and major rule changes. In 1986, Mike Tyson emerged as a fresh new face in the heavyweight division, which had seen a decline in champion quality level after Ali's retirement and, later on, after longtime WBC ruler Larry Holmes' prime. In addition, the IBF and WBO began operating.
