What is the difference between marketing, advertising, and public relations?

[Thanneermalai]

Marketing is a social and managerial function that attempts to create, expand and maintain a collection of customers. It attempts to deliver demand satisfying output through profitable exchanges.

Advertising is paid communication through a non-personal medium in which the sponsor is identified and the message is controlled. Variations include publicity, public relations, product placement, sponsorship, underwriting, and sales promotion. Every medium is used to deliver these messages: television, radio, movies, magazines, newspapers, the internet, and billboards.

Advertising plays a critical role in capitalist economies in creating demand for industrial output. Thus, advertising clients are predominantly profit-seeking corporations. In 1997, in the U.S. alone, over $175 billion USD was spent on advertising. Non-profits are not typical advertising clients, and rely upon free channels, such as public service announcements.

While advertising can be seen as necessary for economic growth, it is not without social costs. Unsolicited Commercial Email and other forms of spam have become so prevalent as to have become a major nuisance of users of these services, as well as being a financial burden on internet service providers.Advertising is increasingly invading public spaces, such as schools, which some critics argue is a form of child exploitation. One scholar has argued that advertising is a toxic by-product of industrial society which may bring about the end of life on earth.

Public relations (PR) is the art of managing communication between an organization and its key publics to build, manage and sustain a positive image.
