branding
the ideas, feelings, or beliefs that people have about a specific product, service, or company. In addition, organizations and other entities such as museums, neighborhoods, groups of people, and countries can be branded. Branding includes the emotional as well as the functional aspects that a person associates with a particular entity or product — aspects which differentiate it from the offerings of other companies or organizations. Since a person’s idea of a brand stems from his or her own feelings and perception, one can say that it is really people who create brands, whereas companies and organizations create products and services.
