A brand is a name, term, design, symbol, or other feature that identifies a seller's product or service as distinct from those of other sellers. The legal term for brand is trademark. A brand may identify a single product, a family of products, or all products of that seller. In the context of product development, a brand can be used to create differentiating value for a product or service through its association with certain qualities or benefits. A well-known example of this is Lux soap, which was created to convey the benefit of 'luxury' to consumers. Similarly, Apple's iPhone has been successful in part because of the strong perception of quality and innovation that the Apple brand conveys. Ultimately, brands represent an important tool for product developers to create value for their offering.
