The document discusses the importance and management of brands. It notes that consumer purchasing decisions are influenced by the name and image of a product, which they retain and reference. A brand represents a product through its image, which can be visual, tactile, sound, olfactory or gustative.

Properly managing brands is thus important for companies to influence consumer choice.
