I'll do a lot for art's sake, but not that. The far greater challenge lies in overcoming the technological limitations of re-reproduction. In practical terms alone, it doesn't matter at all when it comes to text. And only a little bit when we're talking about sound. If there's something vaporous about an image on a computer monitor, new media artists can be grateful that so much groundwork had been laid before them in an effort to excuse the physical presence of an artwork from actual existence.
Conceptual art informs new media art by necessity.
