Genre is a critical tool used to categorize texts based on common elements in order to study them and audience responses. Genre theorists argue that genres are dynamic and constantly changing through negotiation and borrowing conventions from one another, reflecting changes in society. While genres are recognizable through repeated codes and conventions, there is no such thing as a pure genre anymore as they are progressive and ever changing through hybridization. Genre is a useful critical tool as it provides a common framework that can be understood by producers, audiences, and scholars, but it also risks stifling creativity by forcing categorization.
