People do not just go to museums to enjoy an art exhibition only, they want to see also the structures, history and aesthetics features of a local museum, which varies depending on each geographical area. For example, a Western museum is surely different from a museum in an Asian country in terms of building materials and also the ways artworks showed there. If online artwork could satisfy art connoisseurs or history enthusiasts, art exhibitions showing Van Gogh paintings would not be sold out quickly. For those who really know how to enjoy a piece of art, there is nothing that can replace the real-time interaction between the viewers and the real art work.
