I saw it again today on my bottle of Diet Coke. The same folks who brought you “Coke Is It!” “The Real Thing!” and “The Pause That Refreshes!” now bring you this winner — “Live Positively.” Yup, it just falls down flat on its face. And would you believe they have trademarked it too?! Honestly, has someone checked to see whether the people at Pepsi-Cola have successfully sabotaged the latest Coca-Cola tag line?
