Fuchs critically examines Habermas's public sphere in that it addresses only bourgeois communication sphere and proposes alternative media as critical media. His approach is described as:
Herbert Marcuse (1978) argues that art can only be a societal factor as autonomous art. Art would be a part of society, but one that transcends capitalist society by constituting an autonomous sphere of aesthetical forms that transcend capitalism. The beauty of art is not a portrayal of society as it is, but a metaphor for society as it could be. The notion of the autonomy and functionless character of art that Adorno and Marcuse described can be generalized not just for art, but for all alternative media products (including also expression in the area of popular culture, not just the high arts). Alternative media at the form level of the products have a radical potential if they transcend their societal context and have the potential to subvert experience. In the case of critical forms, the subversion of the experience of capitalism is an indirect one, in the case of critical content it is a more direct one. (p. 188)
