Call it the Ad Bowl. Or the Buzz Bowl. Or the BS Bowl. Doesn’t matter, it all boils down to this: Sunday’s Super Bowl is the biggest day of the year for advertisers, some of which dished out $3 million for the chance to reach an audience of 100 million consumers for 30 seconds. At that price — $100,000 a second — the stakes are high. A good commercial can be a triumph, creating just the kind of water-cooler talk that propels a brand to a new level with consumers. A bad commercial? Well, those behind it better start dusting off the old resume.
