We rarely know what "really" happens in these deals.
GM could keep all the internal advertising at no/little cost until 2014 and figured it was worth giving up external sponsorship for the last few years.
Canucks probably game 'em an offer that they couldn't refuse to "request" out of the contract.
A telecom company can do a whole lot more with sponsorship that a car company can't... as BCPhil mentioned.
Robbers should be able to put up the dough for .com
As for the TV ads... the world cup ads are annoying. You have to pay quite a lot to get the games on your phone... almost as much as the data plan itself...
