Street art
In 1999, in Seattle, took place a WTO (World Trade Organisation) summit. There took place big demonstrations. Others summits took place in Prague (2000) and in Genoa (July 2001). The youth that demonstrate during this summit used "Absurd Propaganda", "culture jamming" and other artistic techniques to "reclaim the streets". After the president Georges W. Bush was elected and the 9/11 (September 2001), the absurd propaganda seemed to have a political meaning. So, critics came to the idea to call that phenomenon artivism. Something part art and part activism.
