New campaigns for Diet Pepsi in Canada and the US are launching. For the US they are going to continue on with making the Diet Pepsi can personified as a "star", a la the Super Bowl commercials from earlier this year featuring P Diddy and Jackie Chan. This time they will appear beside Carmen Electra and Kevin Dillon. Supposedly, this is considered humorous - follow this link to one of the print ads.
The Canadian campaign features folks on the street who are asked if there's anything they'd like to have back from their youth.
