In the early 1960s, Professor Neil Borden at Harvard Business School identified a number of company performance actions that can influence the consumer decision to purchase goods or services. Borden suggested that all those actions of the company represented a “Marketing Mix". Professor E. Jerome McCarthy, also at the Harvard Business School in the early 1960s, suggested that the Marketing Mix contained 4 elements: product, price, place and promotion.

Product: The product aspects of marketing deal with the specifications of the actual goods or services, and how it relates to the end-user's needs and wants. The scope of a product generally includes supporting elements such as warranties, guarantees, and support.

Pricing: This refers to the process of setting a price for a product, including discounts. The price need not be monetary; it can simply be what is exchanged for the product or services, e.g. time, energy, or attention. Methods of setting prices optimally are in the domain of pricing science.

Placement: refers to how the product gets to the customer; for example, point-of-sale placement or retailing. This third P has also sometimes been called Place, referring to the channel by which a product or service is sold (e.g. online vs. retail), which geographic region or industry, to which segment (young adults, families, business people), etc. also referring to how the environment in which the product is sold in can affect sales.

Promotion: This includes advertising, sales, promotion, publicity and personal selling. Branding refers to the various methods of promoting the product, brand, or company.

These four elements are often referred to as the marketing mix which a marketer can use to craft a marketing plan.

The four Ps model is most useful when marketing low value consumer products. Industrial products, services, high value consumer products require adjustments to this model. Marketing services must account for the unique nature of services.
