The document discusses Abraham Maslow's hierarchy of needs and Young & Rubicam's 4Cs model of audience classification. Maslow's hierarchy proposes that people are motivated to fulfill basic physiological needs before moving on to more advanced needs. Young & Rubicam segmented audiences according to seven categories that map to different levels in Maslow's hierarchy, including Explorer, Mainstream, and Resigned. Examples are given of how The Mighty Boosh appeals to Explorers and how Toy Story 3 appeals to Mainstream audiences.
