From digital to new media art :

this research, a sample of 3413 auction records from 70 artists known as digital and new media artists is used for the construction of a hedonic price index and to analyze the relative price of the artworks’ attributes. While the actual share of digital and new media artworks in the sample turns out to be too small (2.1%) to yield significant hedonic estimates for digital and new media art, price indices on other subsample segments (paintings, photographs and prints) allow to draw meaningful assumptions. It is indeed suggested that the price index for the photographic market may inform on the ongoing and future development of a market trend for digital and new media art.
