PepsiCo has confirmed that it is to drop its low-calorie drink Pepsi Edge. The beverage sold only 8.6m cases in its first six months since its nationwide release in June last year. US sales of Coca-Cola's C2 low calorie drink mustered 25m cases in the same time frame.

Speaking to the Atlanta Journal-Constitution, Pepsi spokesman Dave DeCecco said that the mid-calorie segment "just hasn't met expectations.

"People give us credit for trying new things," he told the paper. "Consumers are more interested in zero-calorie diet colas, so we're going to focus our energy on Diet Pepsi and Pepsi One."

Pepsi Edge, which contains 50 calories per eight-ounce serving, uses a blend of Splenda (sucralose) and high fructose corn syrup.

As recently after the drink's launch as July last year, analyst Mark Swartzberg warned that mid-calorie colas would be either "slow builds or something closer to dead on arrival."

Coke told the Journal-Constitution that C2 will continue to be available.
