(February 23, 2011) Advertising during the Super Bowl can deliver huge returns for brands and are as closely watched as the game itself. So who wew the big winners among the auto companies running ads on Super Bowl Sunday, Feb. 6?

You Gov BrandIndex, a company that measures brand preception worldwide, has calculated the winners based on "Buzz score" a month prior to the Super Bowl compared to the "Buzz score" two days after the Super Bowl.

Based on the buzz, Kia and Chrysler got the most traction out of their advertising. Kia ranked number three among all advertisers and Chrysler ranked fifth.

Also in the top 10 in improved buzz are BMW (7th) and Honda (10th).

The Pepsi Max "Love Hurts’" ad increased the brand’s Buzz score by an impressive 15.7 points, exceeding last year’s BrandIndex winner Coca-Cola (with 14 points).

Similarly, Doritos boosted its already considerable Buzz score from 23.8 one month ago to a score of 34.1. The brand gained Buzz from its "Pug Attack" and "House Sitting" ads. The former of the two gave advertisers a pause for thought with its micro-budget of $500.

GoDaddy.com, a domain name and web hosting site, adopted a more risqué approach by featuring a number of scantily-clad women. However, the brand still managed to improve on last year’s Buzz score by 4.5 points.
