MUD Turns 30

Massively is reporting that the very first multi-user dungeon (MUD) program has reached its 30th birthday.
Today marks the 30th birthday of the original MUD, created at Essex University by Roy Trubshaw in 1978. We recommend you check out what Richard Bartle -- who worked on later iterations of the project -- has to say about this event, as well as Raph Koster's words on the subject.
Happy Birthday, MUD #1.
