This document provides a review of literature on changing marketing paradigms. It discusses the traditional marketing concept developed by Kotler and Levy in the 1960s, which focused on tangible goods and the 4 Ps. The traditional view is challenged by newer concepts that argue marketing also includes services and is not just goods-dominated. Vargo and Lusch propose enhancing the traditional framework to be more consumer-centric and include marketing of intangible products/services. While the traditional concept still provides a basis, the review concludes it is less relevant today due to changes in technology and markets.
