It's made the US promoters and networks have to seriously up their game which you can see by all the crazy amounts of $$$ being pumped into US boxing recently (Showtime/Fox for example).
Hearn trying to gatecrash the US with his DAZN/Matchroom deal started a domino effect which led to the US powerhouse networks saying "Fuck You" and firing back massively to counter the move.
All brilliant news for fight fans.
The only people really taking Boxing around the planet are the WBSS but even the Winner of that Usyk jumped straight in bed with Eddie Hearn because like him or hate him he's a top top promoter who delivers huge fights.
