Graffiti as Art, Graffiti as History

After I watch the video “Graffiti as Art, Graffiti as History.” I think Graffiti should be as art and history. Graffiti is a way to express our thought to the society. It reflects of complaints and unfair things around our lives. This art consciousness reflects the fact, as long as the event is the existence of such facts, will generate ideas in our mind. Because the graffiti culture is a human culture and human had spread all over the world the graffiti culture also should be worldwide. On the wall or floor that is not possible for the paintings. But, graffiti could do it. That also make graffiti the one and only.
