Supermodel Adriana Lima is sitting in a chair tossing a football and flirting. I’m watching. It’s Victoria’s Secret’s Super Bowl commercial. “It has a very flirty, sexy tone but is different from our other ads,” says Jill Beraud, chief marketing officer. Victoria’s Secret hasn’t advertised during the Super Bowl since 1999, when it wanted to drum up buzz for its fashion show Webcast. The average cost for a 30-second spot during this year’s game is $2.7 million.
