Pepsi-Cola North America today announced that it will add Splenda Brand Sweetener to a newly reformulated Pepsi One, creating a cola with only one calorie.

"Consumers today are performing a balancing act," said Katie Lacey, vice president of carbonated beverages for Pepsi- Cola North America. "They're looking for great-tasting foods and beverages while also trying to limit their calorie intake. That's why we're increasing our focus on diet soft drinks this year, with the reformulation of Pepsi One as a major part of our efforts."

Pepsi is planning a summer-long push behind its entire diet soft drink portfolio that includes new product news, promotional activity, specialised in-store merchandising and increased advertising support.

Beginning this month, reformulated Pepsi One will be available in single-serve 20-oz bottles, 2-litre bottles, and 12-packs and 24-packs of 12-ounce cans. Full national distribution is expected by the end of next month.

An outdoor, print and radio advertising campaign - one of the largest non-television campaigns in Pepsi's history - will support the re-launch of Pepsi One with the theme "Oneify." The brand has partnered with street artist and designer Geoff McFetridge to create a lineup of fictional characters. Beyond billboards and print ads, the characters also will appear in webisodes - short online clips - on McFetridge's designs are also featured on Pepsi One marketing materials including t-shirts, posters and urban advertisements.
