Art's transition to the common man

As I was reading this chapter, I started to really notice how art has transitioned from becoming a "rich man's" thing to something everyone and anyone can be a part of. Even though museums can be accessed by everyone, there still is a sense of class in a museum. Going into a museum means that you are specifically going there to enjoy art. Even though many of them are accessible freely or with a small value, going into a museum means that you have the time to go there, something a common man may not have. Thus, the ant-museum movement in the 1960s and 1970s brought art closer to the people and out of institutionalization.
To go even further into the common world, art started to use surveillance cameras and sensors, so it is how the person acts and reacts that makes the piece. This makes the art more personal to the viewer, and in some cases, more understandable. Speaking from experience, art can sometimes be confusing to the untrained eye. It sometimes seem weird and, not to be harsh, but, unnecessary. The point sometimes is not passed on to some viewers than to others. However, when placing the viewer into the art itself, the viewer seem more connected to the art piece and how the art piece works. As the person's actions make them feel a certain way, the viewer can understand the person's viewpoint. This was exampled excellently in Nauman's "Performance Corridor."

Using art as a way to express political ideas and modern ideas was another way to bring the common man into the world of art. These were things people knew, had an opinion, and talked about. By bringing themes that people knew, artists were able to approach the common man and introduce them to the world of art.
