Genre, hybrid and sub genres

Film genres are identifiable types, categories, classifications or groups of films that have similar techniques or conventions such as;

• content
• subject matter
• structures
• themes
• mood
• period
• plot
• settings
• recurring icons 
• stock characters
• narrative events
• situations
• motifs
• styles
• props
• stars

Genres change and develop because of changes in the period in which the genre is being produced. Genres have also changed overtime with the introduction of brand new technology which allows a film to create new features.

Neale (2003) points out that generic norms and conventions may be recognized and understood by audiences, readers and viewers. Genre frames audience expectations, whereby viewers bring a set of assumptions with them and anticipate that these will somehow be met in the viewing experience, this brings audience pleasure. The demands of commercial practices necessitate that generic forms must somehow ‘guarantee meaning and pleasure’ in order to locate and retain a sizeable audience to justify a return on substantial investment. Steve Neale states that 'genres are instances of repetition and difference' and 'genres are not systems, they are processes of systemisation'.
He also say's that, definitions of genre are historically relative and are therefore historically specific. Believed that there was a system of expectation and that by using own knowledge and applying conventions of the genre, the audience should be able to infer the narrative and storyline of the music video. He also declares that difference is essential to the economy of genre; mere repetition would not attract the audience. 

Hybrid Genre

A hybrid genre occurs when an author or other creative professional attempts to merge two or more genres.

Sub genre

A sub-genre is a sub-category of a specific genre.
