Advertising is an audio or visual form of marketing communication that employs an openly sponsored, non-personal message to promote or sell a product, service or idea. Sponsors of advertising are typically businesses wishing to promote their products or services. Advertising is differentiated from public relations in that an advertiser pays for and has control over the message. It differs from personal selling in that the message is non-personal, i.e., not directed to a particular individual. Advertising is communicated through various mass media, including traditional media such as newspapers, magazines, television, radio, outdoor advertising or direct mail; and new media such as search results, blogs, social media, websites or text messages. The actual presentation of the message in a medium is referred to as an advertisement or "ad" for short.
In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the Öffentlichkeit or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, it has suffered in more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder.
Public relations (PR) is the practice of managing the spread of information between an individual or an organization (such as a business, government agency, or a nonprofit organization) and the public. Public relations may include an organization or individual gaining exposure to their audiences using topics of public interest and news items that do not require direct payment. This differentiates it from advertising as a form of marketing communications. Public relations is the idea of creating coverage for clients for free, rather than marketing or advertising. An example of good public relations would be generating an article featuring a client, rather than paying for the client to be advertised next to the article. The aim of public relations is to inform the public, prospective customers, investors, partners, employees, and other stakeholders and ultimately persuade them to maintain a positive or favorable view about the organization, its leadership, products, or political decisions. Public relations professionals typically work for PR and marketing firms, businesses and companies, government, and public officials as PIOs and nongovernmental organizations, and nonprofit organizations. Jobs central to public relations include account coordinator, account executive, account supervisor, and media relations manager.
From any cross-section of ads, the general advertiser's attitude would seem to be: if you are a lousy, smelly, idle, underprivileged and oversexed status-seeking neurotic moron, give me your money.
Kenneth Bromfield in Advertiser's Weekly, 1962
By saturating the public domain with false sincerity, advertising makes genuine sincerity more difficult.
Avner Offer, The Challenge of Affluence (2006), p. 359.
Advertising is the whip which hustles humanity up the road to the Better Mousetrap. It is the vision which reproaches man for the paucity of his desires.
E.S Turner, The Shocking History of Advertising, 1952
