The concept of publics and related notions such as receivers, audiences, stakeholders, mass, markets, target groups, and the public sphere are central to any discussion of formal communication programs between organizations or other strategic communicators and the individuals or groups with which they strive to communicate. The concept explains why individuals and collectivities of individuals are motivated to communicate for themselves (to seek or otherwise acquire information), with similar individuals to form organized groups, and with formal organizations to make demands on those organizations or to shape the behavior of the organizations. Theories of publics originated in the 1920s as the result of debates over the nature of citizen participation in a democracy, the role of the mass media in forming public opinion, the role of public relations practitioners in the process, and the effects of communicated messages on publics, audiences, and other components of society. J. Grunig developed a situational theory of publics in the 1960s that has served as the most prominent theory of publics for 50 years, and J.-N. Kim and J. Grunig recently have expanded that theory into a situational theory of problem solving. These theories have been used to identify and segment types of publics, to explain the communication behaviors of those publics, to conceptualize the effects of formal communication programs, to understand the cognitive processes of members of publics, and to explain the development of activist groups. Other scholars have suggested additions to these theories or alternatives to more thoroughly explain how communication takes place between members of publics and to identify latent publics that are largely ignored in the situational theories.
