This document discusses genre theory and how genres are used to classify and analyze media texts. Some key points: - Genre refers to types or categories of media texts that share common conventions, themes, and patterns. - Genres act as signifying systems that provide paradigms or templates that media texts can draw from. This allows for a "contract" between producers and audiences about what to expect. - Individual texts may demonstrate generic elements while also differing from other texts in that genre through hybridity or innovation. - Genres are not static but rather develop and change over time through combinations with other genres or becoming obsolete. They frame audience understanding and require cultural knowledge to recognize.
