A détournement (French: [detuʁnəmɑ̃]), meaning "rerouting, hijacking" in French, is a technique developed in the 1950s by the Letterist International, and later adapted by the Situationist International (SI), that was defined in the SI's inaugural 1958 journal as "[t]he integration of present or past artistic productions into a superior construction of a milieu. In this sense there can be no situationist painting or music, but only a situationist use of those means. In a more elementary sense, détournement within the old cultural spheres is a method of propaganda, a method which reveals the wearing out and loss of importance of those spheres."
It has been defined elsewhere as "turning expressions of the capitalist system and its media culture against itself"—as when slogans and logos are turned against their advertisers or the political status quo.
Détournement was prominently used to set up subversive political pranks, an influential tactic called situationist prank that was reprised by the punk movement in the late 1970s and inspired the culture jamming movement in the late 1980s.
Its opposite is recuperation, in which radical ideas or the social image of people who are viewed negatively are twisted, commodified, and absorbed in a more socially acceptable context.
In general it can be defined as a variation on previous work, in which the newly created work has a meaning that is antagonistic or antithetical to the original. The original media work that is détourned must be somewhat familiar to the target audience, so that it can appreciate the opposition of the new message. The artist or commentator making the variation can reuse only some of the characteristic elements of the originating work.
Détournement is similar to satirical parody, but employs more direct reuse or faithful mimicry of the original works rather than constructing a new work which merely alludes strongly to the original. It may be contrasted with recuperation, in which originally subversive works and ideas are themselves appropriated by mainstream media.
