Thomas Hearns
As in the 1980s, the 1990s in boxing's popularity focused on all divisions. When 1980s legends Sugar Ray Leonard, Thomas Hearns, as well as others retired, newer superstars filled the void: Pernell Whitaker, Julio César Chávez, in the early 1990s, Oscar De La Hoya, Félix Trinidad, Roy Jones Jr. and Floyd Mayweather, Jr. in the mid to late 1990s.
