But there was a controversial end to the bout - with NO victor declared.
American former State wrestler turned Vine star, who then migrated to YouTube, Logan Paul, and his United Kingdom counterpart KSI who originally became famous for uploading videos of himself playing Federation Internationale de Football Association on YouTube, have millions upon millions of YouTube subscribers between them.
One ringside judge had KSI ahead by one point but the other two scored it even, meaning a majority draw was declared.
Paul took a strong lead in the first two rounds, but KSI proved he had stamina and managed to fight his way back as their battle went on.
The highly anticipated bout was streamed live on pay-per-view through YouTube, and was attended by about 15,000 fans. We have the exact time for the match and where to watch it live, so without any further delay, let us begin with our post.
After their six round slugfest, the two YouTubers decided they'd "give the fans what they want" in order to finally decide for once and for all who is No.1 when it comes to who is the true boxing champ.
Briton KSI, who boasts 19.4 million subscribers, took on USA star Paul, who has 18.2 million, in the tightly-contested bout at Manchester Arena.
KSI said he would step into the ring with the victor and won against Weller at the Copper Box Arena in February.
In the match against KSI and Paul, thousands of people paid £7.50 each to watch the match n YouTube.
Like any other well-promoted boxing duel, the two vloggers have cultivated lots of tension on social media in the months leading up to the fight.
