The very first, specialized, official (as in organized by professional parties) Star Trek-exhibit, has, outside the "unofficial" science-fiction/Star Trek convention circuit, been the 1992-1994 Star Trek Smithsonian Exhibit. While supported by it, it should be noted that this exhibit was neither produced nor organized by the official franchise, but a purely Smithsonian initiative. It was only after the resounding success of that exhibit that the franchise took over firm control of exhibitions, starting with the 1993 Star Trek Earth Tour.
