Star Wars, Ferris Bueller drive Super Bowl ad buzz

The Super Bowl is still two days away but some advertisers already are looking like winners as their yet-to-be-aired commercials score millions of hits online and rack up pre-game buzz. A teaser for Volkswagen’s ad has drawn more than 11 million viewers on YouTube. The campaign features a pack of dogs barking out a ‘Star Wars’ song, repeating a theme from the company’s well-received ad during last year’s Super Bowl.
