This document discusses the evolution of marketing from early human needs to modern organizations. It explains that early humans obtained basic needs directly through activities like hunting and gathering. As needs grew more complex, barter systems and then monetary exchange developed to allow people to meet needs. This gave rise to markets where goods and services were exchanged. Over time, the focus shifted to better understanding customer needs and developing business organizations oriented around marketing and satisfying customers. The document also outlines different concepts in marketing including production, product, and societal orientations as well as definitions of marketing.
