Billboard hacking or billboard hijacking is the illegal practice of altering a billboard without the consent of the owner. It may involve physically pasting new media over the existing image,[1] or hacking into the system used to control electronic billboard displays. The aim is to replace the programmed video with a different video or image. The replaced media may be displayed for various reasons, including culture jamming, shock value, promotion, activism,[2] political propaganda,[3] or simply to amuse viewers. Billboard hacking started when commercial messages appeared in public space. In the first centuries BC, inscriptions promoting gladiatorial battles on the houses of the wealthiest in Pompeii commonly encountered passers-by who would inscribe their own humorous or insulting responses.[4] The commercialisation of paint markers and spray paint in the 1960s helped popularise the practice. During May 1968 protests in Paris, protesters wrote over billboards to give voice to their messages.[5]

A decade later, the first collectives of billboard hackers emerged. In San Francisco, the Billboard Liberation Front altered the meaning of a diverse range of billboards by selectively adding or removing words. In Sydney, the Billboard Utilising Graffitists Against Unhealthy Promotions, a collective of activists and medical professionals, used spray paint to alter the words and images of billboards promoting cigarettes and alcohol. In 1984, the art collective Frères Ripoulain collaborated with the American artist Keith Haring to paint over billboards on the platform of Metro Dupleix in Paris. The action is followed by an illicit exhibition on the platform. If you need any kind of information on this article related topic click here: Hire a Hacker
