I can not find any data to support your claim, but neither to support the opposite. so who knows. I am pretty sure the 730 million europeans, 1.4 billion chinese, 382 million south americans, and 142 million russians... only a fraction of all these populations who have tv's are more interested in the sports that represent their countries interests. Unless it is the only thing on, snowboarding halfpipe probably isnt on the top of the list for these people. More people own tv's and speak english in china than in all of north america, so that would probably be the main audience outside of north america and europe watching the games, if they can receive any coverage at all that is.
