From sexy Go Daddy ads and video game spots that tell people to "Go to Hell," to Bud Light spots that make a lot of fart jokes, networks have turned down a lot of major advertisers' content. In fact, Go Daddy got 13 ads rejected in 2006 alone.

But a "banned ad" that doesn't get past a netwrok's Standards & Practices Department sometimes does wonders for a company's buzz.

"I remember one year when the networks wouldn't allow one of the Bud Light spots in the game, so Bud actually released it online as, 'the Super Bowl ad the networks wouldn't let you see,'" Tanin Blumberg, an account director at Goodby, Silverstein & Partners and Budweiser Super Bowl ad veteran, told BI. "It was pretty smart … got about 1 million views on YouTube in just a few days."
