Public relations is the art and science of managing communication between an organization and its key publics to build, manage and sustain its positive image. Examples include:
Corporations use marketing public relations to convey information about the products they manufacture or services they provide to potential customers to support their direct sales efforts. Typically, they support sales in the short and long term, establishing and burnishing the corporation's branding for a strong, ongoing market.
Corporations also use public relations as a vehicle to reach legislators and other politicians, seeking favorable tax, regulatory, and other treatment, and they may use public relations to portray themselves as enlightened employers, in support of human-resources recruiting programs.
Nonprofit organizations, including schools and universities, hospitals, and human and social service agencies, use public relations in support of awareness programs, fund-raising programs, staff recruiting, and to increase patronage of their services.
Politicians use public relations to attract votes and raise money, and, when successful at the ballot box, to promote and defend their service in office, with an eye to the next election or, at career’s end, to their legacy.
