The beauty of this is that I get to pull double boycott duty tonight.
Boycott the CBC
Boycott the NHL
For every game cancelled, I pledge not to watch a legally broadcast game when they return. A voice of one is better than no voices whatsoever. Let the NHL know you will boycott their return. Viewer ratings are crucial to how much revenue they can earn from TV rights. You CAN hit both the CBC and the NHL in the pocketbook.
You'll need to do it until the end of the 13/14 season to bother the NHL. That's when their current contract with CBC runs out. Have fun with your boycott though.
