My recent visit to the National Geographic Museum’s exhibit, Indiana Jones and the Adventure of Archaeology, revealed what the modern museum must do to keep the turnstiles turning. And the exhibits, I learned, they are a’changin’.

As a private museum, Washington, D.C.’s National Geographic Museum has to give the people what they want. Under commercial pressure, the amount of information provided by museums is changing, and so is the traditional format. In place of the expected plaques, The Adventure of Archaeology exhibit provides an iPad and a set of headphones. All of the items on display are labeled with three digit codes, which, when punched into the iPad, conjure up a narrator and extra videos to explain what has caught your interest.
