Dick Hebdige said that British Youth are portrayed as either:
"Troublesome youth"
The political representation of youth as posing a threat to society and the status quo. Youth are seen as dangerous and subversive of society's moral values.
"Fun-loving youth"
The commercial representation of youth as going through a rites-of passage style period in their life during which they may behave differently but don't threaten society. They have a need to belong which can be exploited by society for commercial reasons.
