Communication Theory Overview

Communication theory studies the conceptual frameworks used to explain how information, meaning, symbols, and messages are produced, transmitted, interpreted, and socially understood. It examines communication as both a technical process and a human meaning-making system. Across models, rhetoric, persuasion, semiotics, and discourse analysis, the field provides foundational theory for understanding communication in all contexts.
