Most people, when they think of marketing, think of advertising or, possibly, pushy salespeople. However, marketing is much broader, with a focus on the customer and customer satisfaction. Explain the difference between marketing and how it differs from selling or from advertising. In addition, marketing is all about communicating. Discuss how consumers make purchasing decisions based on communications from marketers. Note: in this course, you will want to distinguish whether you are viewing the world as a marketer or as a consumer.
