This document defines audiences and target audiences. It outlines that a target audience is the specific group a media product is aimed at, and audiences can be defined by the product, media type, or pre-existing groups like age, gender, ethnicity. Target audiences are important for media companies to have consumers for their products. The document also discusses categorizing audiences by demographics and other factors, and how audience theory like uses and gratifications and two-step flow can influence how target audiences are defined and will react to media.
