Problem:
Robert Young is not a doctor, but he played one on TV - Dr. Marcus Welby. Sanka created a successful marketing campaign by having "Dr. Marcus Welby" counsel people against the dangers of caffeine and recommend caffeine-free Sanka.
Why do you think this campaign was so successful? Give examples of products that are using this same technique today. Are they as effective as the Sanka campaign? Why or why not?
