But its not just about TV ratings in NA. The NHL has quite a large following across the globe, especially in Europe, and if Bettman wants to give the league even more exposure then he needs to allow its best players to compete in the Olympics.
The BBC coverage of the Olympic ice hockey was fantastic this year, decent commentators were employed rather than the "its a minority sport, get someone cheap and clueless" as has happened before with the BBC and it was well reported in the press. One thing very evident during the games though was the regular referring to the NHL team various players played for and their accomplishments in the NHL as well as wider hockey tournaments.
This kind of exposure on the UKs national, ad-free, media broadcaster is superb. Within the UK ice hockey coverage is generally restricted to ESPN subscribers for NHL or Sky TV for our own domestic hockey league (the EIHL).
The acid test though was the amount of people who I work with who, knowing that I'm a hockey nut, commented on how much they enjoyed watching the Olympic hockey and although they'd never thought of watching it before were getting a subscription to ESPN so that they could continue to watch the some of the best players in the world in the best league.
