In comparison boxings most prolific period was when Tyson came back in 1995 & he had 4 1M+ PPV's in a 15 month period.
Actually I see a 26 month period from Sept. 2009 to Nov. 2011 where there were 7 1M+ PPV's which was probably the height of Floyd & Manny both killing it with PPV's that was probably the most prolific PPV period for boxing.
