Marketing involves creating, communicating, delivering, and exchanging products and services that provide value for customers. It is an activity performed by organizations to achieve business objectives. Marketing creates value for customers, communicates that value, delivers it to the target customer, and generates profit in the process. The definition of marketing has evolved over time from focusing on transactions to emphasizing customer value, satisfaction, and co-creation. Modern definitions recognize marketing as a continuous process that involves interconnected exchanges between organizations and customers.
