Detournement may be understood as the opposite of 'recuperation', the process by which radical ideas and images are commodified and incorporated within the 'safe' confines of 'spectacular' society. With detournement, images produced by the spectacle are altered and subverted so that rather than supporting the status quo, their meaning is changed in order to put across a more radical or oppositionist message. Such a pro-situ technique can be seen in the work of Culture Jammers such as Ad Busters 1, whose 'subvertisements' 'detourn' Nike adverts, for example. In this case the original advertisement's imagery is altered in order to draw attention to said company's policy of shifting their production base to cheap labour cost third world 'Free trade Zones'.
However, the line between 'recuperation' and 'detournement' can at times seem rather thin. Naomi Klein, in her book No Logo, details how Culture Jammers and Ad Busters have been approached (sometimes successfully) by corporations such as Nike, Pepsi, or Deisel, and offered lucrative contracts in return for partaking in 'ironic' promotional campaigns. She points up further irony in the instance of merchandising produced to promote Ad Busters' Buy Nothing day; this, she suggests, may be understood as an example of the recuperation of detournement.
