KFC is considering a new slogan—"So Good," to replace the 50-year-old "Finger lickin' good," the Daily Mail reported. The global fast food chain intends to establish a healthier image in so doing. Colonel Sanders's present slogan has been regarded one of the most successful marketing slogans of the 20th century. Martin Shuker, chief executive of KFC UK and Ireland, said the new slogan is still about the food and will help the company more effectively communicate with the customers regarding health issues.
