I think the value is more interesting to know.
It will be difficult to calculate the total revenue, as the 1.2 million figure is for the world-wide audience and not just for the US market. And if I am not wrong, the fees vary from region to region. That said, I heard that at least in the US the fight was priced below the industry average. Normally the rates would range somewhere between $69 and $99, but DAZN was selling this one for $19.99. So I guess, they earned around $24 million from the PPV, which is less than Canelo's purse ($35 million).
