The American Marketing Association defines a brand as a "Name, term, design, symbol, or any other feature that identifies one seller's good or service as distinct from those of other sellers."
A brand can take many forms, including a name, sign, symbol, color combination or slogan. For example, Coca Cola is the name of a brand make by a particular company. The word branding began simply as a way to tell one person's cattle from another by means of a hot iron stamp. The word brand has continued to evolve to encompass identity — it affects the personality of a product, company or service. It is defined by a perception, good or bad, that your customers or prospects have about you.
In the automotive industry, the terms marque or make are often used to denote a brand of motor vehicle.
A concept brand is a brand that is associated with an abstract concept, like breast cancer awareness or environmentalism, rather than a specific product, service, or business. A commodity brand is a brand associated with a commodity. Got milk? is an example of a commodity brand.
