This document discusses key concepts relating to audience in media studies. It defines audience as the people who consume a media product or text. Media texts have intended target audiences that can be mass/mainstream or niche. Audiences can also be passive or active in how they engage with media. The relationship between producers, texts, and audiences affects how meaning is constructed and understood. Demographic details about audiences like age, gender, social class are important to consider. Theories discussed include uses and gratifications theory, which argues media satisfies audience needs and desires, and Stuart Hall's encoding/decoding model of how audiences can interpret meanings differently than intended.
