Coke Now Second Only to Itself

In a remarkable swap, Diet Coke will leave Pepsi Cola in the dust: its sales are expected to fall more slowly than those of regular Pepsi-Cola, which would leave Diet Coke as the second most popular carbonated soft drink, behind full-calorie Coca-Cola Classic. PepsiCo Inc. and Coca-Cola Co., Inc. have had an extensive rivalry but PepsiCo has seen its share of the market slip in recent years. With overall cola sales dropping, Coke began to pull ahead with 17 percent of the market share in 2009, according to Beverage Digest and The Wall Street Journal. Pepsi-Cola fell 0.5 percent last month while Diet Coke slipped just 0.1 percent.
