The Green Bay Packers may have won the Super Bowl, but the competition for the best commercial from the big game is still being hashed out in homes and offices across the country, perhaps most noticeably on the web.

By the end of Sunday night, the winning company appeared to be Chrysler. Its powerful two-minute commercial garnered the most buzz during the Super Bowl, according to the Brand Bowl, an annual contest powered by advertising consultants Mullen and Radian6 that ranks Super Bowl ads by the amount of positive or negative feedback they receive on Twitter.

Chrysler's commercial attempted to revive the brand and the reputation of Detroit in general, following the painful collapse of the auto industry that left many people in Michigan without jobs. The cinematic commercial featured a cameo from Eminem, the popular rapper raised in Detroit, and debuted a poignant new slogan, "Imported from Detroit," that will be the center of Chrysler's new ad campaign.

While there were certainly funnier commercials, the Brand Bowl data shows Chrysler's message resonated most with viewers. Twitter users posted more than 32,000 tweets related to Chrysler, more than for any other company in the Super Bowl, with the exception of Doritos (PEP). But the feedback from Chrysler-related tweets was more positive than that for any other company on the list, earning it the top spot and pushing Doritos to No. 2.

The force of Chrysler's ad was further demonstrated Monday morning as the phrase "Chrysler 200," the car advertised in the commercial, was the most searched-for term on Google.

But while Chrysler may have won the night, Brand Bowl, which continues to monitor feedback on Twitter, currently shows that Volkswagen now has more tweets and more positive feedback for the day, presumably due to its cute commercial featuring a child dressed as Darth Vader trying to use the Force to move a car. Chrysler is now at No. 2.

As the fight for the winning commercial continues, it is a little more difficult to determine the brand that qualifies as the biggest loser. According to Brand Bowl, the title should go to Cars.com and HomeAway.com, whose ads proved the least effective, generating the fewest tweets overall.

However, an argument could also be made that the biggest loser is actually Groupon.com, even though the company currently ranks third. Groupon's controversial ad effectively tried to turn the cultural crisis in Tibet into a joke for promoting Groupon deals on Tibetan food. Ultimately, most consumers seemed to feel the commercial was in bad taste, and while the ad has more buzz than most today, it also has the most negative feedback of any commercial in the top 10.

So while Cars.com and HomeAway may have spent $3 million each on commercials that ultimately were ignored, Groupon spent that much on an ad to make consumers dislike its company.

Regardless of which ad you think is worse, one point seems clear: Online businesses should stick to advertising online.
