KSI's rematch with Logan Paul sold two-million pay-per-views - which places it in the top five highest selling-fights in history.
YouTube stars KSI - real name JJ Olatunji - and Paul shared a rivalry which sparked the rise of influencer boxing, and dragged a new audience into the sport. The pair first met in a white-collar clash which gripped both the UK and the US, but ended in a draw with a rematch immediately planned.
A second event between the pair was even bigger with the pair electing to fight in the professional ranks, and the sequel was promoted by Matchroom Boxing promoter Eddie Hearn and streaming service DAZN. Hearn has recently confirmed the YouTube meeting is one of the most successful events he has ever staged on pay-per-view.
