Cadillac Cans Led Zeppelin, Unveils New Campaign

Cadillac is going for a more warm and fuzzy ad campaign and Led Zeppelin's "Rock and Roll" song won't be a part of it. Commercials featured the song for five years in the "Break Through" ads but with Cadillac's agency move has come an ad campaign shift.

Cadillac recently move to ad agency Modernista!, dropping agency Leo Burnett. Some industry pros say the main reason for the switch came after the Super Bowl XL commercial flop, where an Escalade appeared on a model runway.

More on Cadillac's Ad Campaign:

Others predict Cadillac's global marketing chief Liz Vanzura switched Cadillac to Modernista! because of her background working with Hummer. Modernista! previously produced spots for the Hummer.

Modernista! has announced its new campaign for Cadillac. The theme, "Life. Liberty. And the Pursuit" will be used.

Vanzura released a statement saying that Cadillac's research showed younger consumers know about the Escalade but don't know of the other types of vehicles Cadillac sells. The new campaign is focused on those younger consumers but Vanzura says the ads will still appeal to Cadillac's older and loyal customers as well. Print, television, outdoor and interactive ads will all begin in mid-August.

GM still remains with Leo Burnett but Cadillac's ad budget to Modernista! is worth $300 million. In 2005, Cadillac reportedly spent $240 million in advertising.
