Where in Time is Carmen Sandiego? began in the fall of 1996, replacing the former PBS Carmen show, Where in the World is Carmen Sandiego?, both produced by WQED Pittsburgh and WGBH Boston. This version had one of Carmen's cronies going back in time to steal something that would affect the course of history.
The show featured an opening round in which contestants answered questions about History. In the second round, contestants ranked eight events from most recent to earliest. Then in the final round, one contestant had to answer six multiple choice questions asked by Carmen in 90 seconds by running around the set through the gateways of time. A correct answer allowed the contestant to pass through it. If the contestant answered incorrectly, they must manually open the gate. If the contestant passed through 6 gates in time, he or she won a computer system.
