Resumen
As a variety of marketing environmental factors have changed and evolved over the past century, so has the definition(s) of marketing. The author provides a chronological listing of the various (and popular) definitions of marketing that have been used in the marketing literature over the past 100 years. The contents of the manuscript represent an important resource for marketing students, faculty, and practitioners in developing a richer understanding of the development and evolution of marketing as both an academic discipline and a business practice.
