Marketing is such a wide area that I hope you will find many angles and perspectives to talk about this MAJOR business disciplines. Here again are some SUGGESTED topics:
Which area of marketing would you be interested in as a career path?
Which particular product or service do you find most fascinating and why?
Have you ever seen a commercial that is so obviously misleading that it could be considered unethical?
Do you think that you personally are very susceptible to being influenced by promotional activities (e.g., sales, advertising, etc.)?
Which other areas of business do you think marketing folks mostly interact with?
