Bush in 30 seconds ad rejected by Viacom.

Viacom's CBS today rejected a request from liberal group MoveOn to air a 30-second anti-President Bush ad during the Super Bowl, saying the spot violated the network's policy against running issue advocacy advertising.

A CBS spokesman said the decision against broadcasting the spot had nothing to do with either the Super Bowl or the ad's specific issue but was because the network has had a long-term policy not to air issue ads anywhere on the network.

Are anti smoking ads 'issues' by the way? Just wondering. How about anti-terrorism ads? Is that an 'issue advocacy advertising'? Don't litter? Is that 'advocacy advertising'? Whats an issue? Someone help me out here....
