The public relations industry describes its own activities as being based on two premises:
Fraser P. Seitel, in his Public Relations textbook, says that “Much more than customers for their products, managers today desperately need constituents for their beliefs and values.” Public relations provides publicity for products and services but it also sells corporate images, goals and philosophies, political programs, and social ideas.
In the case of a business-managed democracy public relations is also about ensuring "public and political compliance" with the political agendas and policies advocated by business interests.
