In a marketing campaign created by Y&R, Sao Paolo, Brazil. Ironage, an isotonic sports drink made in Brazil, targeted athletes who constantly strive to exceed their own personal best. In addition to print ads featuring athletes, Y&R promoted the brand strategically in places where customers were most likely to congregate – namely, gyms, parks, and health clubs. There, they introduced vending machines, dubbed “Pulse Machines.” Consistent with the brand’s slogan “Keep Moving,” the machines read the customer’s heart rate with each use. The higher their heart rate, the bigger their discount on a bottle of Ironage. The Pulse Machine challenged the competitive spirit of these athletes and turned them into word-of-mouth promoters of the brand as they compared their pulse readings.
