Support, or endorsement, refers to the act of publicly expressing approval or backing for a person, product, or idea. This can occur in various contexts, such as politics, where a candidate may receive support from influential figures or organizations, enhancing their credibility and appeal to voters. In marketing, endorsements often involve celebrities or experts promoting a product, which can influence consumer behavior. When a well-known figure endorses a brand, it can lead to increased trust and sales, as consumers may associate the product with the endorser's positive qualities or reputation.
