This document discusses definitions of popular culture and its relationship to culture and art. It provides six definitions of popular culture: (1) culture that is popular or liked by many, (2) culture that is not considered "high culture", (3) culture that is mass-produced and consumed, (4) culture of the common people, (5) culture that involves struggles between social classes, and (6) culture that is postmodern and critiques distinctions between high and low art. The document examines how popular culture can be analyzed and critiqued through the example of the TV show The Simpsons.
