This document discusses different perspectives on genre theory. It begins by defining genre as a distinctive type of text, and notes that genres have sub-genres and are dynamic, evolving processes rather than static systems. Generic conventions include common narrative elements, settings, costumes and props across different media. Genres are cultural categories that exist within industries, audiences and society. They use familiar codes and conventions to appeal to audiences and allow audiences to choose media based on genre. Genres also provide audiences with different types of pleasures and evolve over time as society changes.
