From what I could find, the PPVs cost 18 GBP (~$24):
Froch Vs. Groves 2 had 900k.
Floyd vs. Hatton had 1.3m
Froch vs. Kessler had 250k
Joshua vs. Whyte had 400k
Joshua vs. Martin had 400k+
Lewis vs. Tyson had 750k
To compare to Golovkin's PPV with Lemieux, that show generated ($60 x 150k) $9M. In order for him to generate the same $9M from PPV revenue, he needs to sell 375K PPVs on Sky.
Him to generate? He's the B-side, he's the Lemieux in this scenario.
I have lil knowledge of past UK PPV numbers & price points so I got no idea, but I expect it'll do middle of the road numbers/revenue. Not gonna suck or be great basically. Whatever those numbers actually represent in the UK market I got no clue.
Froch-Groves II -- The PPV sales were around 900,000 at £16.95
