Graffiti by Banksy
Underground art is exemplified in what was called the underground press, magazines like Oz, International Times, East Village Otherand , The San Francisco Oracle and in the comix of West Coast America. Its precursors were the Beat Generation and the Paris Existentialists.
These days the term underground art is used to describe a subculture of art, like graffiti art or comic strip art. Since the late 1990s the internet has become a forum for underground art thanks to its ability to communicate with a wide audience for free and without the support of an art establishment.
