Chevy Super Bowl Ad Challenge, Week 4

(CBS)  In the "Chevy Super Bowl College Ad Challenge," Chevy invited college students nationwide to submit ideas for a Super Bowl ad featuring Chevy's new line of cars and crossovers.

Chevy says more than 800 teams from some 200 schools applied.

Judges used these criteria: creativity and originality, 50 percent; relevance to theme, 40 percent; and clarity of expression, 10 percent.

The winning ad, created by a student team and produced by Chevrolet, will air during Super Bowl XLI this Sunday, on CBS. The Early Show will interview the winning team live on Monday, Feb. 5.

On Wednesdays this month, The Early Show showed video mock-ups of some of the ads that came in from students around the nation, and you got to pick the ones you liked best.

We organized them into four categories: "Best Use of Car," "Most Humorous," "Best Football-Themed," and "Most Offbeat."

You can also see behind-the-scenes footage of the five teams selected by Chevy as finalists, as they finessed and then presented their ideas to compete for the top spot. Log on to cbs.com/chevy to see those reality webisodes.
