The two chapters that make up Part 1 establish a foundation for the entire textbook. Chapter 1 provides a contemporary definition and description of personal selling and describes information-age personal-selling career opportunities. Sales-training programs offered by academic institutions, sales-training companies, and employer-provided sales training are also presented. Chapter 2, in response to the developments associated with the information economy, presents the evolution of contemporary selling models that complement the marketing concept. Chapter 2 also introduces the major themes that connect all of the chapters.
