PepsiCo is taking a hold of the fast growing on-the-go market. Pepsi-Cola North America saw sales up 18% year-on-year, led by products such as Aquafina, the number one single-serve bottled water brand, and single-serve dole juices. The on-the-go format now accounts for more than a third of the 15 billion liters of bottled water bought in the US each year. More impressively, it accounts for nearly half of the all the carbonated drinks bought.
