In 1993, Edutainment was the promise of computers. We had an old XT that my sister took to college that fall, and we were shopping for a 486. Encarta and National Geographic CD-ROM based titles were everywhere. Every demo in every computer store let you play with these seemingly-limitless repositories of information. It was mind-blowing -- complete with short postage stamp videos for select subjects!
It would be fascinating to look back at all of the titles available, but rich multimedia was finally here, and it died as quickly as it had arrived, as people moved to AOL, CompuServe, and the Internet instead.
