Floyd Mayweather’s dull but clear victory over Manny Pacquiao in what was dubbed the ‘Fight of the Century’ has officially smashed the all-time boxing pay-per-view record becoming the richest fight in boxing’s history.

Early reports from broadcasters Showtime and HBO suggest the event generated more than 4.4m buys and more than £255m in U.S. pay-per-view revenue.

The bout that was almost 6 years in limbo nearly doubled the previous record of 2.48m buys generated by the 2007 fight starring Oscar De La Hoya v Floyd Mayweather.

Moreover, this latest welterweight world title spectacle almost tripled a record £96m in US pay-per-view revenue that was generated by Mayweather v Saul Alvarez in 2013 – a fight that Mayweather won unanimously on points.

The gate takings for the celebrity-packed arena in Las Vegas produced in excess on £45m – more than tripling the previous boxing record of £13m – for the sport as well as Las Vegas.

This megafight between also set new revenue records for closed circuit admissions around the US.

It was distributed in 175 countries worldwide, available in nearly 75 per cent of the world's territories, setting a new revenue record for international distribution – by some margin.

The fight itself was a dud, a typical masterly display by boxing’s pound-4-pound king Mayweather.

Fight of the Century it was not, but it certainly sold like it was.
