Advertising is a form of communication intended to persuade an audience (viewers, readers or listeners) to purchase or take some action upon products, ideals, or services. It includes the name of a product or service and how that product or service could benefit the consumer, to persuade a target market to purchase or to consume that particular brand. These brands are usually paid for or identified through sponsors and viewed via various media. Advertising can also serve to communicate an idea to a mass amount of people in an attempt to convince them to take a certain action, such as encouraging 'environmentally friendly' behaviors, and even unhealthy behaviors through food consumption, video game and television viewing promotion, and a "lazy man" routine through a loss of exercise . Modern advertising developed with the rise of mass production in the late 19th and early 20th centuries. Mass media can be defined as any media meant to reach a mass amount of people. Several types of mass media are television, internet, radio, news programs, and published pictures and articles.
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; or new media such as websites and text messages. Advertising may be placed by an advertising agency on behalf of a company or other organization.
Non-commercial advertisers that spend money to advertise 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.
In 2007, spending on advertising was estimated at more than $150 billion in the United States and $385 billion worldwide
