Public Relations Often public relations are described as the effort to influence the public or relevant parts of it by representing self-interests to reach certain goals. This view of PR is most commonly found, when acting within the economic sphere. On the other hand organizations like the PRSA (Public Relations Society of America) as well as several PR theorists and practitioners see themselves as social engineers, responsible for societal harmony. "Public relations help our complex, pluralistic society to reach decisions and function more effectively by contributing to mutual understanding among institutions. It serves to bring public and public policies into harmony...", the PRSA announced in one of their official statements on public relations.

Centralization of the Content Industry Following the 1980s a sweeping restructuring of commercial media power has happened. While some firms have grown through expansion others extended through mergers and acquisitions. Examples are Time & Warner & Turner & AOL; Viacom & Paramount & Blockbusters or News Corp. & Triangle & 20th Century Fox & Metromedia TV. In recent years those developments have led to the rise of transnational media giants, resulting in the domination of the global media system by about ten huge conglomerates. These have interests in numerous media industries, ranging from film production, magazines, newspapers, book publishing and recorded music to TV and radio channels and networks, but also include retail stores, amusement parks and digital media products. Behind these firms are about three or four dozen smaller media companies, which primarily engage in local, national or niche markets. In short, the overwhelming majority of the world's content production facilities and distribution channels lies in the hands of approximately fifty enterprises.
