One press conference uploaded to Paul's vlog channel was watched over 14 million times.
The last event of this kind, headlined by KSI vs. fellow YouTuber Joe Weller, reportedly garnered less views than KSI and Paul's meeting.
They did. If anyone was in any doubt about YouTube's place in society after 1.8 million watched February's bout for free, perhaps they'll pay attention now viewers have spent more than $8 million - plus ticket and merchandise sales - on small-screen superstars.
Paul and KSI traded wild swings throughout the fight, which devolved into a dirty, ugly clinch-fest as both fighters grew worn out.
"Both fighters struggled with the pace of the six-rounder but Logan was able to drop his hands for long spells, safe in the knowledge KSI posed no threat", the report noted. Logan Paul put a "cool million" on himself to knock KSI out in the third round.
Millions tuned in online to see a tightly-contested bout between the two rivals that resulted in a majority draw.

The Liberal leadership is shaping up to be a threeway contest with Julie Bishop poised to make a run for the top job. It was the seventh prime minister in 11 years in a remarkable revolving door at Canberra's parliament house.
Paul, who hit controversy after he posted a video which showed the body of an apparent suicide victim in Japan, said: "I think it's what the people want".
Both YouTubers will undoubtedly take a rest before any official arrangements are made.
It all started when two other YouTubers - Joe Weller and Theo Baker, AKA Malfoy - went into the ring past year, and KSI said he would fight the victor.
Fight, fight, fight! Logan Paul is set to square off against KSI in the boxing ring today.
At first people thought this was just a publicity stunt for views and the fight event would never materialize, but as the two sides went back and forth for weeks and started training seriously people started to realize it was no joke. And with the rematch on the works, is it possible that their next fight would finally be taken seriously by the people?
