Not art

In the movie Art School Confidential, the main character has a goal to become "the greatest artist of the 21st century". However, his drawings are extremely traditional portraits of pretty girls.

I was thinking about this, and I realized - very few of the painters considered "important" in the last century painted anything traditional. In fact, what many of the "important" artists created was not even considered art at the time. The public at the time looked at these paintings and said "What?? That's not art - art has to have a subject, can't be copied from a photo, has to be of high craftmanship, etc."

Here are a few examples of art that was not considered art when it first came out:

Abstract art

Action painting

Cubism

Expressionism

Impressionism

Lowbrow

Minimalism

Photorealism

Pop Art
