What helps audiences recognise genre?

select texts on basis of genre, often because texts are arranged at retail outlets by genre (just pop along to HMV). Also, certain genres are considered appropriate to certain ages/genders in society, and choices are made accordingly eg teen movie, 'chick flicks' have systems of expectations about the content and style of a text, according to its genre. This enables them to take particular pleasures in the text, those of repetition, and of predicted resolution. Pleasure may also be drawn from differences. Identify with repeated elements in generic texts and may shape their own identity in response (eg fans of a particular genre of music dress in a specific way - metalheads in their band t-shirts, for instance)
