Commercial ads often seek to generate increased consumption of their products or services through "branding," which associates a product name or image with certain qualities in the minds of consumers.
On the other hand, ads that intend to elicit an immediate sale are known as direct response advertising. Non-commercial advertisers who spend money to advertise items other than a consumer product or service include political parties, interest groups, religious organizations and governmental agencies. Non-profit organizations may use free modes of persuasion, such as a public service announcement. Advertising may also be used to reassure employees or shareholders that a company is viable or successful.
