I was reading Advertising Age's Marketing 50 Awards, a list of the top 50 marketers of the year. The publication gave a well-deserved nod to Gatorade's chief marketing officer Cindy Alston. As a business reporter, I've talked to many executives and Cindy is really at the top of the game. The magazine gives Alston the credit for launching the lighter tasting Rain -- a line that, as you might know, I'm not the greatest fan of -- but also provided a great insight: PepsiCo's Gatorade could soon take out Coca-Cola's Sprite. Apparently Sprite the No. 5 beverage brand and Gatorade currently stands at No. 6. What's very interesting about this is the fact that years ago a marketing firm gave Gatorade the first dibs on the slogan, "Obey Your Thirst." Gatorade of course turned it down and it became Sprite's slogan, while Gatorade took up "Is It In You?"
