Marketing is communicating the value of a product or service to customers, for the purpose of selling that product or service.
Marketing techniques include choosing target markets through market analysis and market segmentation, as well as understanding consumer behavior and advertising a products value to the customer. From a societal point of view, marketing is the link between a societys material requirements and its economic patterns of response. Marketing satisfies these needs and wants through exchange processes and building long-term relationships. Marketing blends art and applied science (such as behavioural sciences) and makes use of information technology.
