"Genre" is the term used to show a set of media products that share similar codes and conventions.
Genre occurs when a set of conventions is used repeatedly and is successful with audiences, for example:
Explosions + Bruce Willis + guns + bad guys + difficult romantic relationship = ACTION MOVIE
OR
Boy + Girl + funny but wise best friend + boy and girl have a misunderstanding + boy and girl make up = ROMANTIC COMEDY
Audiences gain pleasures from understanding the codes and conventions of particular genres:
- familiarity
- predictability
- empathy
- escapism
- "repetition and difference" (Steve Neale 1980): the audience wants to be surprised, but within the parameters of what they expect
- being able to share the experience with others
- hybrid genres offer the audience new content and experiences while staying within a set boundary
Clear genre conventions are a way of guaranteeing to the audience a set of experiences as a means of getting them to spend money and time.
Your magazine must display clear features in terms of photography, star, costume, performance, lighting, colour, mode of address, fonts etc.
Tho illustrate this further, the link below plays on the audience knowing, and disliking, how rom coms work. Have a look :-)
