The Pepsi-Cola Co. has had a less controversial year than its main competitor, but it's been one filled with product launches and organizational changes of its own. Beginning the summer selling season with limited-edition Mountain Dew LiveWire and launching Vanilla Pepsi at the end of the summer, the Purchase, N.Y.-based company recorded positive sales results in 2003 in all channels, except for mass merchandise, according to IRI and ACNielsen. While Coca-Cola suffered a slight decrease in category volume share, Pepsi reported a slight gain. Although the brand's regular colas felt a 3.2 percent hit from last year, Pepsi flavors, including the Sierra Mist family of products, and Diet Cherry Pepsi, experienced increased sales of 144 percent and 68.9 percent, respectively.
