Some models are general in the sense that they aim to describe all forms of communication. Others are specialized: they only apply to specific fields or areas. For example, models of mass communication are specialized models that do not aim to give a universal account of communication. [21] Another contrast is between linear and non-linear models.
Mass communication began when humans could transmit messages from a single source to multiple receivers. Mass communication has moved from theories including the hypodermic needle model (or magic bullet theory) to more modern theories such as computer-mediated communication. [citation needed]
Gerhard Maletzke applied the SMCR model to mass communication in his 1978 book The Psychology of Mass Communication. He sees communication as a form of persuasion. He discusses factors influencing the behavior of the communicators and the outcome of the communication, like the image source and receiver have of each other.
Lasswell and others have used his model beyond the scope of mass communication as a tool for the analysis of all forms of verbal communication. [2] [12] [10] This is also reflected in the fact that some theorists employ his model in their definition of communication in general. [2]
Most theorists identify Schramm's model with his 1954 book The process and effects of mass communication and present it as a reaction to earlier models developed in the late 1940s. [2] [3] [15] However, marketing scholar Jim Blythe argues that Schramm's model is of earlier origin and was already present in Schramm's 1949 [a] book Mass ...
Models of communication are often categorized based on their intended applications and how they conceptualize communication. Some models are general in the sense that they are intended for all forms of communication. Specialized models aim to describe specific forms, such as models of mass communication. [23]
The two-step flow of communication model hypothesizes that ideas flow from mass media to opinion leaders, and from them to a wider population. It was first introduced by sociologist Paul Lazarsfeld et al. in 1944 [4] and elaborated by Elihu Katz and Lazarsfeld in 1955 [5] and subsequent publications. [6]
One key activity in communication theory is the development of models and concepts used to describe communication. In the Linear Model, communication works in one direction: a sender encodes some message and sends it through a channel for a receiver to decode. In comparison, the Interactional Model of communication is bidirectional. People send ...
