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.
 Public relation is an action of convincing people.
 The PR person talks with others that make them think about the things the person wants them to think, and the people regard the person as their believes.
