This video from 1974, which is making the rounds on the web this week, documents the first computer assisted pizza order. The experiment enabled the speech impaired subject, Donald Sherman, to place an order for a large 16-inch pepperoni, mushroom, ham and sausage pizza to be delivered to the Michigan State University Artificial Intelligence Computer Lab, which developed the technology that made the call possible. It took several attempts for a pizzeria to accept the order, with a hangup from Domino's, before Mr. Mike's Pizza patiently took the order. From a quick Google search it looks like any pizzeria by that name in the Lansing area is long gone.
