Not sure if Lipton is reading their tea leaves right on this one. They are partnering with Pepsi to market carbonated tea. But not just any tea - sweetend fruity carbonated tea. This article cites declining interest in mainstream soft drinks for the reasoning behind offering these new drinks. I think most people are turning away from the mainstream soft drinks to avoid all the sugar & syrupy artificially flavored crap.
A carbonated, plain, sweetened or unsweetened natural tea might have been a better idea. Or at least another flavor in the line up.
