A printed plaque installed in 1995 still works exactly as intended today. An interactive touchscreen exhibit installed the same year almost certainly does not, since the software it depended on has likely stopped being supported, the hardware has failed, or both. Museums investing heavily in new media are taking on a maintenance problem that older, simpler formats never had to face.
Why this problem gets underestimated during planning
Exhibit budgets typically account for the upfront cost of building an interactive display, and far less consistently account for the ongoing cost of keeping it running years later — software updates, hardware replacement, and the specialized knowledge required to fix a system built on technology that may no longer be common by the time it fails. A projection system installed today, celebrated for how effectively it engages visitors, can become a genuine liability within a decade if nobody planned for its eventual obsolescence.
