Public relations is defined as a deliberate, planned effort to build and maintain mutual understanding between an organization and its publics. PR functions include financial PR, consumer PR, crisis PR, industry relations, and government relations. Traditionally, PR communicated policies and programs, but now takes a more marketing-oriented role operating within marketing departments. PR professionals determine public attitudes, design proactive PR plans, execute those plans using tools like news releases, press conferences, displays and events, and determine plan effectiveness. Forming a positive corporate image involves managing internal factors like identity, advertising, branding, and employees, as well as external factors like industry reputation, country of origin, and word of mouth.
