Commodities are fungible goods that are indistinguishable across producers and have prices determined by supply and demand. Many iconic brands originated as commodities. Branding transforms a commodity into a differentiated product by establishing an idea or experience through advertising. Commodity advertising aims to expand the market through reminder and precipitation functions, while brand advertising focuses on persuasion and reinforcement to gain market share. For commodities as experience goods purchased frequently in small amounts, branding delivers emotional value to turn them into brands through celebrity endorsements or emphasized attributes, even if not objectively measurable. Successful branding of commodities depends on how easily advertising can communicate differentiating product attributes.
