It wasn't your typical over-the-top Super Bowl commercial.

The animated spot featured an Asian panda bear complaining to his wife about a lack of customers at the family business, Ling Ling's Bamboo Furniture Shack. A psychic panda appears and suggests that the couple turn to for free sales leads.

The commercial, which aired during Super Bowl XLII in February 2008, was criticized for evoking racist stereotypes. But the 30-second spot succeeded in attracting attention to the small company, a unit of Infogroup in Omaha, Neb.

It's certainly not cheap to advertise during the Super Bowl -- a 30-second spot during this year's game between the Pittsburgh Steelers and the Green Bay Packers costs around $3 million, and the slots have been sold out since October.

But the Super Bowl broadcast represents an unparalleled opportunity to reach a mass audience, marketing experts say. Last year's game was seen by 106.5 million viewers, and Sunday's broadcast is expected to attract as many as 110 million, according to MayoSeitz Media.

That's why this year's game has again attracted some of the nation's biggest advertisers, including Anheuser-Busch InBev (BUD, news), Best Buy (BBY, news), and General Motors (GM, news). The commercials provide fodder for office chit-chat, which encourages some advertisers to be outrageous and edgy.

"Super Bowl advertising is an event," says Lonny Strum of the Strum Consulting Group in Voorhees, N.J. "Even if you're a medium-sized company and advertising (during the Super Bowl broadcast), it gives you the opportunity to appear as a mega-company."

As a result, smaller companies are regularly willing to gamble on the expense of producing and airing commercials for the Super Bowl broadcast. It's a gamble that has clearly paid off for HomeAway, an online vacation-home marketplace, and other companies. For others, including Salesgenie, a Super Bowl commercial that courts controversy and risks a thumbs-down from critics can still pay off.

"A lot of these smaller companies want exposure very quickly, so there's nothing like the Super Bowl to do that," said Brian Steinberg of Advertising Age, a trade publication for marketing professionals.

Go Daddy, a provider of Web domain names and hosting packages, was a virtual unknown before its foray into Super Bowl advertising in 2005. The Scottsdale, Ariz., company is now known for its saucy ads featuring race-car driver Danica Patrick and others.

Founder and CEO Bob Parsons has vowed that the company's campaign for Sunday's Super Bowl broadcast will be as brash as ever and will feature Patrick and the latest "Go Daddy Girl," Jillian Michaels, a personal trainer best known for her starring role on the reality TV show ''The Biggest Loser."
