With cable TV sports channels and internet, pretty much any sport that is televised can be watched and learned. It all depends on how much you want to watch and learn.
I lived in England for 6 years as a kid so I know cricket. To be honest though I enjoyed rounders more than cricket. Rounders is like the ancestor of baseball for those who don't know.
Only hear about chess boxing when I google for it specifically and yet always get surprised to see how it continues to be more popular globally and my country (Russia) also has a fair amount of people involved into it.
