Ad Track: The Super Bowl edition

— -- In its first-ever Super Bowl appearance, sportswear maker Under Armour will use the world's biggest advertising stage to introduce Prototype, a cross-trainer shoe, in a bold bid to compete with Adidas and Nike.

Launching pad.

"We're redefining ourselves to the outside world," CEO Kevin Plank says. "We're sticking a flag in the ground."

The ad will direct viewers to underarmour.com to order the shoe, available May 3.

Jeter jitters.

Another new product in the Feb. 3 game will be Gatorade's G2 low-calorie sports drink. One G2 ad will feature New York Yankees player Derek Jeter.

He was at work last week trying to help Gatorade get a head start on getting a bang for its Super Bowl ad buck with a press event in Manhattan's Herald Square.

The Bronx Bomber said he'll first see his finished ad while watching the game on TV in Las Vegas. He said he had no jitters until he heard that other Super Bowl ad celebs include stars such as Madonna and Justin Timberlake.

"Now, I'm nervous," he said. "Maybe I'll get up and go to the bathroom (during his ad) so I won't have to hear any jeers."

We can do that.

Watch out, Madison Avenue, Under Armour isn't the only Super Bowl advertiser that decided it's talented enough to make its own ads. Victoria's Secret and sales-lead website Salesgenie.com also are creating Super Sunday ads in-house.

"I know who the customers are and what resonates with them," says Salesgenie.com founder Vin Gupta, who wrote his company's commercials. "These are not great ads, but they are good enough. Someone who watches the ad(s) will know the service we are promoting."

Super stock performance.

Maybe Super Bowl advertisers will get their money's worth — even at up to $2.7 million this year per 30 seconds of commercial time.
