In this chapter you have learned that the purpose of this book is to introduce you to the academic field of Communication by setting a foundation of communication history and study in the first six chapters, followed by the chronological presentation of some of the major specializations that make up this academic field.

Smith, Laswell, and Casey offer a simple definition of communication study: “who says what, through what channels (media) of communication, to whom, [and] what will be the results” (121). Now you can provide an answer to those who ask you what Communication study is about. Our definition of communication, the process of using symbols to exchange meaning, allows you to understand how we use this term throughout the book. The linear and transactional models of communication act as a visual representations of both communication study and communication. Finally, you are now aware of the importance of studying communication: that it impacts your personal, social, and professional life.
