Distinguishing Radio, Television, and Film: Structure, Functions, and Societal Impact
1. INTRODUCTION
Radio, television, and film are three of the most influential mass media platforms. They all aim to communicate messages to an audience, but they differ in technology, presentation, audience interaction, and societal influence. Understanding these differences is crucial for anyone studying broadcasting and film.
2. STRUCTURE
