In its brief history Internet art has moved from being the concern of a few brilliant amateurs to a position of prominence in the art world. While much material art seen in conventional galleries feels disengaged with the world, caught up in weary variations of art-world concerns, Internet art is often humorous, socially aware and politically active. Accessible and jargon-free, this book explores the character of this new, dematerialised online art and the Internet's transformation into an arena for consumerism. The author suggests that this new art may have radical implications for the way in which we conceive of art's authorship and ownership and more fundamentally, our understanding of what is and what is not art.
