Apparently Fox banned this ad because they were afraid to piss of Coke and Pepsi, major advertisers for the network. The Ad was banned, not because it was too seductive, but because of the line "Sorry Coke and Pepsi". I guess freedom of speech doesn't extend to commercials if the network thinks it will piss off competitors who spend more money.
For the 2011 Superbowl season, instead of plunking down the big bucks for a Superbowl ad, like their competitor GoDaddy, Network Solutions decided to create an "unsensored" parody video called "Go Granny", to make fun of the GoDaddy Girls Commercials. This video would have been banned from the Superbowl.
