Adorno explored change in the mode of production domination in the sphere of culture, especially music and literature, not in the sphere of work. "Culture' does not merely designate the realm of consumption, nor the organisation of leisure according to the principle of commodity exchange. Adorno developed a general theory of culture predicated on his use of Marx's theory of value by transcribing the range of Marx's categories of production (composition), distribution (reproduction), exchange (the culture industry) and consumption (reception). "Production' does not refer to the organisation of work or manufacturing; "reproduction' does not refer to technology; "the culture industry' does not refer to industry.
