Brewster-
I'm not a lawyer, but I think that if they made money using CBS's trademark, then CBS is entitled to compensation or supression. Would you open a burger joint and call it eatMcDonalds and expect to get away with it?
Better yet, how would Casablanca feel if another sportsbook used the name: betcbs.org or betcbs.tv or betcbs2.com, etc.
Brewster, maybe you should start up "Kasablanca Gaming".
P.S. For the bashers waiting in the woodwork, I'm just commenting on the concept of trademarks, and trying to show how it can backfire if you try to abuse it.
