if you are looking at number of viewers its hard to beat shoe shinning:bbb However, it is hard to compare across continents because everyone has a different business model. As we know the only thing that matters in business is the bottom line. $$$$ . . . ask any fighter whether they would rather make 30mill with a million viewers or 1 mill with 300mill viewers. So the answer is clear, today Mayweather is the biggest draw. that all being said . . . Shoe shinning (if he keeps winning) will be the future box-office king!
