The marketing mix and the 4 Ps of marketing are often used as synonyms for each other. In fact, they are not necessarily the same thing.
"Marketing mix" is a general phrase used to describe the different kinds of choices organizations have to make in the whole process of bringing a product or service to market. The 4Ps is one way – probably the best-known way – of defining the marketing mix, and was first expressed in 1960 by E J McCarthy.
The 4Ps are:
Product (or Service).
Place.
Price.
Promotion.
