Jermell Charlo’s Knockout Win Over Brian Castano Is Showtime’s Most-Watched Fight In Almost Three Years

Jermell Charlo becoming the first undisputed light middleweight champion – in the four-belt era – isn’t the only history that was made on Saturday.

The rematch between Charlo and former WBO champion Brian Castano recorded Showtime’s biggest audience for live boxing in nearly three years. Nielsen Media Research showed that the fight averaged an audience of 756,000 and peaked at 832,000.

Charlo won by 10th round knockout at Dignity Health Sports Park in Carson, California.

Showtime’s numbers for a live boxing event weren’t that high since Deontay Wilder’s first-round knockout of Dominic Breazeale in May 2019. The stoppage recorded an average audience of 795,000 on Showtime’s channel and a combined average viewership of 886,000.

But there wasn’t much time for that audience since Wilder knocked out Breazeale in just two minutes and 17 seconds.

Saturday’s rematch also topped their first match in July, which was Showtime’s most watched boxing main event of 2021. It averaged a viewership of 422,000 and a peak of 536,000.
