Since the retirement of Lennox Lewis in 2004, the heavyweight division has been criticised as lacking talent or depth, especially among American fighters. This has resulted in a higher profile for fighters in lower weight classes, including the age-defying middleweight and light heavyweight champion Bernard Hopkins, and the undefeated multiple weight division champion Floyd Mayweather, Jr., who won a 2007 split decision over Oscar De La Hoya in a record-breaking pay-per-view event. Billed as the "fight to save boxing", the success of this event shows that American boxing still retains a considerable core audience when its product is of descent from the American continent.
