According to the University of North Carolina at Pembroke, internal and external publics are public relations components. Internal publics are agency employees, whereas external publics are individuals and organisations from outside the agency with whom it does business.
Customers, present and prospective workers, investors, vendors, suppliers, media, government, and opinion leaders comprise an organization’s important publics. Public relations is to build and maintain relationships between an organisation and its publics. Public relations establishes favourable relationships between an organisation and its internal and external publics through the use of activities, goods, and communications. Event management, publicity, and publication layout are three popular public relations techniques.
