UFC PPV buys have long been something for fans to pour over and get obsessed with, so UFC 170 with Ronda Rousey at the helm was immediately one to get obsessed over. Why? Because people want to see if Ronda Rousey really is as huge of a star as the UFC is painting her. The initial estimates for UFC 170 were between 300,000 to 400,000 buys and guess what? It fell exactly into that realm according to Dave Meltzer.
Meltzer cites UFC 170 with an estimated 340,000 PPV buys for Ronda Rousey vs. Sara McMann. To put that into perspective, UFC 169 did an estimated 230,000 buys according to Meltzer. The PPV market isn’t exactly red hot right now. [source]
