No, not a joke at all. Millions of people around the world tune in to watch the massive boxing matches even if they don't follow the sport. Many of my friends will go out on a night a big boxing match is on just to watch it in a pub instead of paying for it on PPV. Floyd "Money" Mayweather is massive, especially in the US. Plus the fighting sports seem to be very popular with the females as well, they seem to get a kick out of watching ripped sweaty men kicking 7 shades of **** out of one another.
There's also the likes of Lebron James and Kobe Bryant as basketball is huge over there. I've never watched a basketball game in my life yet I've heard of these two.
Believe it or not Boxing doesnt even come close, coverage wise.
It may appear as though its hugely popular (and I know they stage a lot in the US especially the "glamour" fights) but I can gaurentee a lot of people on the street around the world wouldnt know a boxer 's name from Adam Sandler lol (obviously a picture may give the game away, but a name is as good a test as any).
Bolt isnt getting anywhere close either - yes he is an amazing sprinter, who has just done the double double (defending 100m & 200m Olympic titles) but I still reckon he isnt known as much as Federer or Woods (or Beckham) on a global scale
Well known or not, he's now locked into the history books. To defend the 100m, 200m and 4x100m Olympic titles, and to hold the world records in all 3 is amazing. We may never see that done again.
Not wishing to discredit bolt at all, as he did amazingly well - but I would be astounded if it wasnt done again in my lifetime (if I life to 70 which isnt unreasonable, that would be 30 years)
Bolt is unlikely to be in Rio , and the amount of runners Jamaica and USA pump out, I would even be surprsed if its not done within 3 further Olympic cycles (considering the amount of runners who do 100m and 200m and therefore the relays too - I think its most of them)
It does of course depend on the traxk / conditions which cant be predicted (ie London was designed to be a "speed" track, whichdidnt help the distance runners)
