   Originally coined in a 1982 paper by researchers John Shoch and Jon
   Hupp of the Xerox Palo Alto Research Center, the term "worm" is
   derived from "The Shockwave Rider," a 1972 science-fiction novel
   about the downfall of an Orwellian society caused, to some degree,
   by a "tapeworm" program that liberated data as it proliferated
   through networks.

   Shoch and Hupp had needed a way to automate the installation of
   Ethernet-performance measuring tools on more than 100 computers at
   Xerox PARC, so they turned to a class of programs that could send
   and install themselves across the network. The programs installed
   quickly, could be updated and ran automatically.

   "What we called the worm is a kind of distributed computation that
   is a really interesting and powerful thing," said Shoch, now a
   general partner at venture capital firm Alloy Ventures in Palo
   Alto, Calif.

   But to the pair's dismay, when their program developed a bug, the
   bad code automatically spread across the network as well.

   "The worm would quickly load its program into (the computer); the
   program would start to run and promptly crash, leaving the worm
   incomplete--and still hungrily looking for new (computers)," Shoch
   and Hupp wrote in a 1982 paper on the experiments with that and
   other self-spreading programs.

   "The embarrassing results were left for all to see: 100 dead
   machines scattered about the building."
