What's so new about new media art?

Susan Elizabeth Ryan closes her article about new media art with a quote from Jacques Derrida that says "One never sees a new art, one thinks one sees it, but a 'new art,' as people say a little loosely, may be recognized by the fact that it is not recognized." So what's new about writing about new media art? This article speculates on the terms new media art/multimedia art/variable media art. I found the article interesting when Ryan discussed the origins of multimedia art, but I was disappointed with all of the discussion on the appropriate terms for art. I'm not at all interested in classifying types of art and labeling it. I guess art historians thrive on the classification of style and periods of art, but that's because they get paid to write and discuss it. Often, these people are classifying art but not creating it.

I guess I was expecting more because of the title of the essay. I thought that I would either be reading a sarcastic piece on the fact that nothing is new anymore, or an information-packed article on the artists creating art. However, it focused more on questioning the classification of art rather than analyzing new media art.
