A Usenet newsgroup is a repository usually within the Usenet system, for messages posted from users in different locations using the Internet. They are discussion groups and are not devoted to publishing news. Newsgroups are technically distinct from, but functionally similar to, discussion forums on the World Wide Web. Newsreader software is used to read the content of newsgroups.
A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan area. The term MAN is applied to the interconnection of local area networks (LANs) in a city into a single larger network which may then also offer efficient connection to a wide area network. The term is also used to describe the interconnection of several LANs in a metropolitan area through the use of point-to-point connections between them.

The alt.* hierarchy is a major class of newsgroups in Usenet, containing all newsgroups whose name begins with "alt.", organized hierarchically. The alt.* hierarchy is not confined to newsgroups of any specific subject or type, although in practice more formally organized groups tend not to occur in alt.*. The alt.* hierarchy was created by John Gilmore and Brian Reid.
CIX is an online based conferencing discussion system and was one of the earliest British Internet service providers. Founded in 1983 by Frank and Sylvia Thornley, it began as a FidoNet bulletin board system, but in 1987 was relaunched commercially as CIX. At the core of the service were many thousands of "conferences" - groups established by users to discuss particular topics, conceptually not unlike newsgroups but limited to CIX subscribers. These conferences still exist today although the CIX service has since expanded to include many other features. The service is funded by a monthly subscription charge rather than by advertising.
On Usenet, the Usenet Death Penalty (UDP) is a final penalty that may be issued against Internet service providers or single users who produce too much spam or fail to adhere to Usenet standards. It is named after the death penalty, as it causes the banned user or provider to be unable to use Usenet, essentially "killing" their service. Messages that fall under the jurisdiction of a Usenet Death Penalty will be cancelled. Cancelled messages are deleted from Usenet servers and not allowed to propagate. This causes users on the affected ISP to be unable to post to Usenet, and it puts pressure on the ISP to change their policies. Notable cases include actions taken against UUNET, CompuServe, Excite@Home, and Google Groups.
Google Groups is a service from Google that provides discussion groups for people sharing common interests. Until February 2024, the Groups service also provided a gateway to Usenet newsgroups, both reading and posting to them, via a shared user interface. In addition to accessing Google groups, registered users can also set up mailing list archives for e-mail lists that are hosted elsewhere.
Eternal September or the September that never ended is Usenet slang for a period beginning around 1993 when Internet service providers began offering Usenet access to many new users. The flood of new users overwhelmed the existing culture for online forums and the ability to enforce existing norms. AOL followed with their Usenet gateway service in March 1994, leading to a constant stream of new users. Hence, from the early Usenet point of view, the influx of new users in September 1993 never ended.

Usenet, USENET, or, "in full", User's Network, is a worldwide distributed discussion system available on computers. It was developed from the general-purpose Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980. Users read and post messages to one or more topic categories, known as newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are threaded, as with web forums and BBSes, though posts are stored on the server sequentially.
