This document discusses several theories for categorizing audiences: - Burton's theory defines audiences by the particular products they consume and their pre-existing social groups. - Hartley expands on this by identifying 7 subjectivities including gender, age, family, class, nation, and ethnicity that influence audience preferences. - Fiske looks at additional factors like education, religion, political views, region, and urban vs. rural location that provide more detailed audience segmentation. - Social status classifications also segment audiences based on occupational class. - Maslow's hierarchy of needs is also relevant as motivations like physical needs, security, love and esteem influence the types of content different audiences prefer.
