I still have my boxed copy of Encarta 2001. The interactive world atlas was the best feature! Miles ahead of everything at the time. Multiple layers of stats from population to weather to languages etc https://youtu.be/zsbShjlh6xk?si=4U47LILUmKPfXgPY&t=320
CD ROM encyclopedias were only really viable when dial up speeds limited the amount of multimedia content on the internet. Both Microsoft and Britannica were victims of internet encyclopedias. And now static internet based encyclopedias are themselves under threat of personalised AI content as well. The pursuit of knowledge keeps changing what knowledge itself looks like.
