On March 30-31, 2001, the Solomon R. Guggenheim Museum in New York hosted a conference entitled "Preserving the Immaterial: A Conference on Variable Media." The conference made public for the first time the Guggenheim's Variable Media Initiative: a pioneering effort to explore the issues surrounding, and to find solutions to problems arising from, art made in inherently ephemeral media. This effort is spearheaded by John Hanhardt, the Guggenheim's Senior Curator of Film and Media Arts, and Assistant Curator Jon Ippolito.
