Contemporary art market in China has influenced Taiwan¡¦s art market recently. The number of auction houses and new art galleries has been increased in Taiwan. The researcher discovered that the work of New Media Art has represented by galleries gradually. However, the sale of work of New Media Art is still limited. The reason is that the work of New Media Art lacks of physical form, and it can be easily replicated, which is contradicting to the traditional collectors¡¦ perspectives. This research attempts to understand how the New Media Art be promoted through galleries¡¦ perspectives. Three questions are raised in this research: First, How is the partnership between galleries and new media artists? And what service galleries provide to the collectors? Second, how galleries manage the product of New Media Art? And how it is different from managing other traditional art works? Third, how galleries interact with external environment, such as competitors, governments, enterprises, museums, academic departments, curators and auction houses? And how these environmental factors influence galleries while managing the work of New Media Art? Cross-case studies are used as the research methodology. Eleven galleries were interviewed, including East Gallery, IT Park, Lin & Keng Gallery, Galerie Grand Siecle, Main Trend Gallery, AKI Gallery, Chi-Wen Gallery, VT Artsalon, Soka Contemporary Space, Project Fulfill Art Space, and Gallery 100 (by establishing time). Methods of data collection include observation, document analysis and interviews. Triangulation is used to increase the credibility and trustworthiness. In conclusion, this research shows the New Media Art is still one of the commodities that the galleries sell. In order to respond to variable formats of New Media Art, galleries need to take different actions to promote them.

Fourth, encouraging hi-tech corporations to sponsor hardware, and be responsible for equipment repairing. Galleries will only need to responsible for software of the work. Fifth, art education is good way to increase consumers¡¦ understanding on New Media Art. Galleries should connect with the museums effectively.
