Communication can be described as information-related behavior which is a necessary life process. There are three common settings of communications: Interpersonal, machine-assisted, and mass communication. Popular theorists of communication are Harold Laswell, Shannon & Weaver, Wilbur Schramm, Katz & Lazarsfeld, Westley & MacLean, and Kincaid.
Model of Laswell
Laswell developed a model in 1948 which focused on verbal messaging. It deals with the question: “Who says what to whom in what channel with what effect?” Thus, it emphasizes speaker, message, and audience and provides a more generalized view of goal or effect of communication.

Three Models of Schramm
Schramm’s third model is a further development in terms of feedback that the destination sends to the source.
The Westley-MacLean Model states that communication begins with a potential message. Then, an advocate is involved and selects an event to form a new message. The model accounts for both, interpersonal and mass media communication. It broadened and elaborated the feedback concept.
