Advertising is a form of communication intended to persuade its viewers, readers or listeners to take some action. It usually includes the name of a product or service and how that product or service could benefit the consumer, to persuade potential customers to purchase or to consume that particular brand. Modern advertising developed with the rise of mass production in the late 19th and early 20th centuries.

Commercial advertisers often seek to generate increased consumption of their products or services through branding, which involves the repetition of an image or product name in an effort to associate related qualities with the brand in the minds of consumers. Different types of media can be used to deliver these messages, including traditional media such as newspapers, magazines, television, radio, outdoor or direct mail. Advertising may be placed by an advertising agency on behalf of a company or other organization.

Organizations that spend money on advertising promoting items other than a consumer product or service include political parties, interest groups, religious organizations and governmental agencies. Nonprofit organizations may rely on free modes of persuasion, such as a public service announcement.

Money spent on advertising has declined in recent years. In 2007, spending on advertising was estimated at more than $150 billion in the United States and $385 billion worldwide, and the latter to exceed $450 billion by 2010.
