What is Culture Jamming?

Culture Jamming is when you use posters, billboards or other things you find in the environment and change them to subvert them or give a different message. An example would be the art of Princess Hijab,  who painted black veils on posters of women in Paris, making a statement about commercialism and the objectification of women, as well as a protest against the banning of the hijab in France.  http://www.theguardian.com/artanddesign/2010/nov/11/princess-hijab-paris-graffiti-artist

This artist has used the police department logo to make a statement.
