Sprite launches first global ad campaign, hoping to 'spark" sales

Sometimes it's hard to be the old soda on the block. Since its introduction in 1961, Sprite -- the lemon-lime soda brand owned by Coca-Cola -- has quenched the thirsts of millions, but it hit a slump as it entered middle age. The problem? A younger lemon-lime upstart called Sierra Mist, rolled out by PepsiCo in 2000, has quickly gained market share, according to Advertising Age.

Could advertising be both the source of and the solution for Sprite's woes?
