Coca-Cola ( KO) has remained a leading worldwide brand because its inexpensive product has become a habit for consumers and benefited from its consistency of product and name recognition. According to BrandZ, Coca-Cola is the sixth-most valuable brand, with a value of nearly $74 billion, an 8% increase over last year. Separating its product line, traditional Coke was tops among soft drink brands, followed by Diet Coke, which surpassed Pepsi to take the No. 2 spot. "The shift reflected an ongoing move to diet in the face of health and obesity concerns," BrandZ says. "It happened in a year when the ongoing slide in soda sales slowed, perhaps because consumers needed a pleasurable break from the barrage of headlines about unemployment and the need for sacrifice." Coca-Cola, according to the report, was aggressive with traditional advertising and, with Pepsi, "relied on innovative social media that asserted the strength of their brands and the emotional bond with customers."
