The concepts of spectacle and détournement are closely associated with the Paris-based postwar avant-garde movement known as the Situationist International. Spectacle is meant to work as a concept that critiques not this or that aspect of media culture, but its totality. It reveals the spectacle as the double, in the world of consumption, of capitalist commodity production. Détournement is the practice which opposes spectacle by refusing all forms of private property in the production of cultural works. While the Situationist International expired as a movement in 1972, these concepts were subsequently taken up by others, although most often shorn of the revolutionary impulse their linkage was meant to forge. This is why it is important to stress the origins of these concepts in both Western Marxism and also in the radical avant-garde movements of the prewar period. Guy Debord, a central animating presence in the Situationist International, was drawing on militant Marxist thinkers such as Georg Lukács and Henri Lefebvre, as well as the lesser-known Belgian branch of the Surrealist avant-garde. Understood as keys to a unified critical theory and practice, spectacle and détournement can be retrieved from merely descriptive studies of literature and media, and also from more narrowly formalist avant-garde literary practices.
