The Interpersonal Computer
When launching the NeXT computer, Steve Jobs said that the '80s had been the decade of the personal computer, while the '90s would be the decade of the interpersonal computer — a computer used for communicating between people. He talked about how introducing (multimedia) email and mailing lists into NeXT had changed how the company was run.
Actually, he didn't mention mailing lists — the term wasn't in common use yet in the context of email — with LISTSERV only a couple of years old and Majordomo still a few years in the future.
Some years later, Sun would adopt "the network is the computer" as its slogan, but NeXT had already been pushing that vision for a long time. Today's Internet comes close to doing on a global scale what NeXT was doing on corporate and school networks in 1988.
