What is subvertising? Broadly, it is the art of making spoof advertisements from corporate and political actors with the aim of making the public think of the damage caused by those actors. The term was coined in 1991 by the cultural critic Mark Dery, and is a portmanteau of the words subvert and advertising.
Subvertising can take place physically on our high streets, with billboards hi-jacked to give an alternative message. They can also appear digitally as memes and spoof political slogans.
