Subculture often reads like a textbook on semiotics. There is much emphasis placed on material objects and the conflicting ways in which they are defined and used. Of particular concern to Hebdige is the way in which one culture dominates another by deciding the meaning of common objects. What Hebdige presents is a revolution of language, as subcultures dare to redefine objects by changing their use or context. In this way, argues Hebdige, a subculture might bring change to the mass culture of which it is part.
