• On January 27, 1986, a meeting at USC-ISI replaced the .ARPA structure with 6 functionally organized top level domains. Representatives of the four major networks were Ken Harrenstein (ARPANET,) Dan Oberst (BITNET,) Craig Partridge (CSNET,) and Mark Horton (UUCP.)
• Global domains created were .COM, .EDU, .GOV, .MIL, .ORG, and .NET. 2 letter country codes, based on ISO 3166, were added as an afterthought but not expected to be popular. (Steve Kille promptly pronounced .GB unusable and created .UK.)
• Each of the four major networks was authorized to cooperate to register second level domains.
• At lunch break, the participants were horrified to learn of the Challenger space shuttle explosion.
