Usenet
Usenet () is a type of discussion system on computers. It was created from the Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis began the idea in 1979. The system was created in 1980. People read and post messages (called articles, postsor news) to one or more categories. These categories are called newsgroups. Usenet is similar to a bulletin board system (BBS) in many ways. It is the precursor to Internet forums. Discussions are threaded but posts are stored in order of when they were posted.
