This document discusses public relations (PR) and its role. PR is defined as a strategic communication process that builds mutually beneficial relationships between organizations and their publics through planned and sustained efforts. The key publics that an organization communicates with through PR include employees, media, investors, government, suppliers, and consumers. PR differs from advertising in that it aims to build trust and understanding with these publics rather than directly promoting to target audiences. The roles of PR include being an advocate, communicator, problem solver, and opinion collector for an organization. An example PR campaign for Nescafe is summarized that used a web game and viral video clips to promote understanding of coffee production and engage the public.
