contact this guy and complainCBS Has Refused To Air MoveOn.Org's Contest-Winning Ad "Child's Pay" during the Superbowl
Mr. Leslie Moonves
CBS Chairman and CEO
There's also a list of superbowl advertisers to boycott and an online petion to sign as well.
Pretty much a cop out, however they are more than wiling to except commercials from the white house during the game but when it comes to this they just plain refuse it if enough people complain then surly they will allow it.
