Subvertising is a portmanteau of subvert and advertising. It refers to the practice of making spoofs or parodies of corporate and political advertisements. Subvertisements 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 or culture jamming. 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. It cuts through the hype and glitz of our mediated reality and, momentarily, reveals a deeper truth within."
