A recent development, with the expansion of the web, is the establishment of virtual museums. Online initiatives like the Virtual Museum of Canada and the National Museum of the United States Air Force provide physical museums with a web presence, as well as online curatorial platforms such as Rhizome.
Some virtual museums have no counterpart in the real world, such as LIMAC (Museo de Arte Contemporáneo de Lima), which has no physical location and might be confused with the city's own museum. The art historian Griselda Pollock elaborated a virtual feminist museum, spreading between classical art to contemporary art.
Some real life museums are also using the internet for virtual tours and exhibitions. On March 23, Whitney Museum
in New York organized what it called the first ever online Twitter museum tour.
