Subvertising

Subvertising (a portmanteau of subvert and advertising) is the practice of making spoofs or parodies of corporate and political advertisements. The cultural critic Mark Dery coined the term in 1991. Subvertisements are anti-ads that deflect advertising's attempts to turn the people's attention in a given direction. According to author Naomi Klein, subvertising offers a way of speaking back to advertising, ‘forcing a dialogue where before there was only a declaration.’ They may take the form of a new image or an alteration to an existing image or icon, often in a satirical manner.

A subvertisement can also be referred to as a meme hack and can be a part of social hacking, billboard hacking or culture jamming. Although he rarely altered physical ads, American performance artist Joey Skaggs' media interventions function as subvertisements. By parodying authoritative narratives and co-opting mass communication tools, he delivers countercultural messages which align with subvertising's intent to disrupt and critique dominant cultural messages using the very channels that propagate them.

According to Adbusters, a Canadian magazine and a proponent of counter-culture and subvertising, "A well-produced 'subvert' mimics the look and feel of the targeted ad, promoting the classic 'double-take' as viewers suddenly realize they have been duped. Subverts create cognitive dissonance, with the apparent aim of cutting through the 'hype and glitz of our mediated reality' to reveal a 'deeper truth within'.

Subvertising is a type of advertising hijacking (détournement publicité), where détournement techniques developed in the 1950s by the French Letterist International and later used by the better-known Situationist International have been used as a contemporary critical form to re-route advertising messages.
