Brandalised is an anti-advertising movement. It is a form of creative activism that uses subvertising to alter and critique corporate advertising by creating parodies or spoofs to replace ads in public areas. The art is typically intended to draw attention to political and social issues such as consumerism and the environment. Advertisements produced by the Brandalism movement are silk screen printed artworks, and may take the form of a new image, or a satirical alteration to an existing image, icon or logo. The advertisements are often pasted over billboards, or propped under the glass of roadside advertising spaces.
