In a wise move, CBS have rejected a commercial for the gay dating site Man Crunch (eh?). Given that this would have been a LOT more controversial than say.. pro-choice v/s anti-choice (isnt anti-choice a choice some people make?), we can see the rational behind this.
Needless to say, these folks also know that getting rejected from the superbowl commercials saves you money and creates more viral buzz than actually paying for and having your commercial show during the game.
However, it was ok in 2007, since the ad was not really about a gay dating site and was about Snickers. Everyone loves snickers!
