Washington (AFP) - There's the new "Wonder Woman" actress in action and a sexed-up Mr. Clean. And some political messages too -- but only if you pay close attention.
Sunday's Super Bowl is not just the biggest US sporting event, it's also the most important event of the year for advertisers. For some, the clash of top marketers overshadows the premier American football game.
The Super Bowl is expected to draw more than 110 million US viewers, and a 30-second spot on the Fox network will cost an estimated $5 million.
This offers both challenges and risks for brands, according to Tim Calkins, professor at Northwestern University's Kellogg School of Management, who leads a Super Bowl ad review with his students.
