Marketing is "the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large."

For business to consumer marketing it is "the process by which companies create value for customers and build strong customer relationships, in order to capture value from customers in return". For business to business marketing it is creating value, solutions, and relationships either short term or long term with a company or brand. It generates the strategy that underlies sales techniques, business communication, and business developments. It is an integrated process through which companies build strong customer relationships and create value for their customers and for themselves.

Marketing is used to identify the customer, satisfy the customer, and keep the customer. With the customer as the focus of its activities, marketing management is one of the major components of business management. Marketing evolved to meet the stasis in developing new markets caused by mature markets and overcapacities in the last 2-3 centuries.^{[citation needed]} The adoption of marketing strategies requires businesses to shift their focus from production to the perceived needs and wants of their customers as the means of staying profitable.^{[citation needed]}
