Supermodel Kate Upton appears in an online Mercedes-Benz video in a low-cut top. A man wakes up with his face covered in smeared lipstick and his hands bound in furry handcuffs in a Gildan Activewear clip. And "30 Rock" star Tracy Morgan seemingly curses in a spot for Kraft's Mio flavored drops. Super Bowl advertisers no longer are keeping spots a secret until the Big Game. They're releasing online snippets of their ads or longer video trailers that allude to the action in the Game Day spot. It's an effort to squeeze more publicity out of advertising's biggest stage by creating pregame buzz. Advertisers are shelling out $4 million to get their 30-second spots in front of the 111 million viewers expected to tune into the game. But they're looking for ways to reach even more people. About half of more than 30 super Bowl advertisers are expected to have teaser ads this year, up from 10 last year, according to Hulu, which aggregates Super Bowl ads on its AdZone Web site. ___ Hostess set to announce bidder for Twinkies NEW YORK (AP) â¿¿ The indestructible Twinkie appears to be one step closer to a comeback.
