Virtual worlds and online multiplayer games have been around in some fashion or other since the mid-1970s. One man (and friends) now boldly choose to document this history at Virtual Worlds Timeline

This project will be interesting to follow as it gets off the ground. Documenting historical events in virtual space presents unique challenges of data collection, access and quality as well as examining the biases inherent in people’s perspectives.
For anyone interested in historical research in a new medium, a chance to test theories of practice if I ever saw one, this is something to watch!
