I don't know exactly how much is 75 dollars for a PPV in the US during these times.
One thing they have to consider is if what ppl always tell about PPV's is true, namely that lot of these buys actually covered by more viewers cause ppl make fight parties and split the price or something then I can imagine that during the times - when many ppl don't eve like to go out to shop not to hold parties - less ppl will buy PPVs just for themselves.
I hope it does good though, if I know it right the UFC did alright with its PPVs during the pandemic but not sure how are their numbers compared to their usual ones
