:USENET: /yoos'net/ or /yooz'net/ [from `Users' Network'] n.
A distributed {bboard} (bulletin board) system supported mainly
by UNIX machines. Originally implemented in 1979--1980 by Steve
Bellovin, Jim Ellis, Tom Truscott, and Steve Daniel at Duke
University, it has swiftly grown to become international in scope
and is now probably the largest decentralized information utility
in existence. As of early 1993, it hosts well over 1200
{newsgroup}s and an average of 40 megabytes (the equivalent of
several thousand paper pages) of new technical articles, news,
discussion, chatter, and {flamage} every day.

bboard: /bee'bord/ [contraction of `bulletin board'] n.
1. Any electronic bulletin board; esp. used of {BBS} systems
running on personal micros, less frequently of a USENET
{newsgroup} (in fact, use of this term for a newsgroup generally
marks one either as a {newbie} fresh in from the BBS world or as
a real old-timer predating USENET)....
