This document discusses the evolution of communication theory models from Aristotle's original linear model to more modern conceptualizations. Aristotle's model proposed a straightforward, one-way transmission of information from speaker to audience. Later models, like those developed by Shannon and Weaver, incorporated the concept of "noise" or interference. Structural models accounted for the relationship between sender and receiver, and how their interaction results in a cyclical communication process. The most influential current model focuses on how messages are encoded as "representations" of reality, and how understanding the cultural context helps the receiver connect with the message.
