We will develop a working definition of marketing. We will illustrate that marketing is simply a process or set of activities whose goals are to provide goods and services to individuals. We will look at the notion of individual needs as the driving force behind marketing. We will also look at the notion that the entire process requires an exchange between individuals, one that focuses on buying and selling of goods and services. We will learn that marketing is a key function in business and an important one, whether in a planned economic system or in a market-driven economic system. We will then take marketing one step further to demonstrate its various areas of specialization, such as social marketing, the marketing of individuals, organizational marketing, and real property marketing.
