This chapter discusses the nature and origins of marketing. Marketing covers a wide range of essential business activities which ensure that customers can obtain the products and services that they want and need, when and how they want them. The most common applications of marketing are consumer marketing, business-to-business marketing, service marketing, not-for-profit marketing, and international marketing. Since the 1960s, marketing has used the four Ps of Price, Place, Product, and Promotion to deliver its marketing objectives and this has now been expanded to include another three Ps of People, Physical Evidence, and Process. The chapter also includes an assessment of what is customer value.
