Can't be 100% sure but I work it out with some loose math that it's around 12.5 million give or take.
Accoring to Wiki the TV share of the country 39% of the population. The population is 95 million. 39% of 95 million is 37 million. The rating point for the fight was 34%. So that's 34% of 37 million which leaves us with 12.5 million.
We'll see about Donaire's fight. Donaire, when matched against a notable opponent, does around one million viewers. However, is Nishioka really notable? He's the best fighter in the division, but American audiences don't really know him.
The fight driving that card is Rios-Alvarado. I'd be surprised if it did 1.6. I'll say it's closer to around 1.3 or 1.4. Either of those would be great.
They make the claim boxing failed in TV ratings when in fact it did the best ratings on CNBC in 2 years. These articles are a total crock of ****e. The boxing TV ratings are listed here as a big success yet some writers are trying to say it failed. Boxing got more viewers on CNBC than some sports did on NBCS during the Olympics.
