The relationships between advertising, marketing, and public relations are not well defined. In general, however, advertising and public relations are considered components of marketing. Marketing is the craft of linking producers of a product, service, or idea with existing and potential consumers. Marketing techniques are most generally associated with transactions in capitalist economies, but they are also applied in religion, politics, and other aspects of public life. Advertising is part of an overall marketing strategy, and it involves the paid promotion of goods, services, ideas, and companies by an identified sponsor. Public relations connotes a broad spectrum of communication either within a group (e.g. company, political party, scientific community) or between that group and specific publics with the intent of informing and influencing their behavior and perceptions in ways that are favorable to that group.
