Marketing has been practiced since ancient times and has been thought about
almost as long. Yet, it is only during the 20th century that marketing ideas
evolved into an academic discipline in its own right. Most concepts, issues and
problems of marketing thought have coalesced into one of several schools or
approaches to understanding marketing. In this article we trace the evolution of
10 schools of marketing thought. At the turn of the 20th century, early in the
discipline’s history, the study of functions, commodities, and
institutions emerged as complementary modes of thinking about subject matter and
became known collectively as the ‘traditional approaches’ to
studying marketing; shortly thereafter the interregional trade approach emerged.
About mid-century, there was a ‘paradigm shift’ in marketing
thought eclipsing the traditional approaches as a number of newer schools
developed: marketing management, marketing systems, consumer behavior,
macromarketing, exchange, and marketing history. During the mid 1970s, three of
the modern schools - marketing management, consumer behavior, and exchange -
underwent a ‘paradigm broadening’. The broadened paradigm
has bifurcated marketing thought from the conventional domain of business
behavior to the much broader domain of all human social behavior. Thus, at the
beginning of the 21st century marketing thought is at a crossroads.
