Massimo d'Amore, the divisive figure at the center of many of PepsiCo's biggest marketing campaigns over the past several years, is retiring. According to executives familiar with the matter, the retirement of Mr. d'Amore, 56, was to be announced today. The announcement dovetails with a much-anticipated investor meeting in New York where PepsiCo is expected to announce an infusion of marketing spending. The company has been under pressure from analysts who have been calling for increased investment in the North American beverage category. (Advertising Age)
