This is the most extensive newsgroup hierarchy outside of the Big 8. Examples include:
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.
The Great Renaming was a restructuring of Usenet newsgroups that took place in 1987. B News maintainer and UUNET founder Rick Adams is generally considered to be the initiator of the Renaming.
The Usenet newsgroup alt.religion.scientology started in 1991 to discuss the controversial beliefs of Scientology, as well as the activities of the Church of Scientology, which claims exclusive intellectual property rights thereto and is viewed by many as a dangerous cult. The newsgroup has become the focal point of an aggressive battle known as Scientology versus the Internet, which has taken place both online and in the courts.
news.admin.net-abuse.email is a Usenet newsgroup devoted to discussion of the abuse of email systems, specifically through email spam and similar attacks. According to a timeline compiled by Keith Lynch, news.admin.net-abuse.email was the first widely available electronic forum for discussing spam.
alt.sex.stories is a Usenet newsgroup for erotic stories created on May 7, 1992, by Tim Pierce as an alternative to pre-existing alt erotica newsgroups. The group was initially unmoderated, a feature that was not shared by some of the other Usenet or altnet newsgroups. This feature allowed for greater user freedom.
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.
Sporgery is the disruptive act of posting a flood of articles to a Usenet newsgroup, with the article headers falsified so that they appear to have been posted by others. The word is a portmanteau of spam and forgery, coined by German software developer, and critic of Scientology, Tilman Hausherr.
alt.suicide.holiday is a Usenet newsgroup. Its original purpose was to discuss the relationship between suicide rates and holiday seasons. However, it later evolved into a broad discussion forum where suicidal people can openly share their struggles or research suicide methods. Some participants are not suicidal, but post to provide psychological support or advice on how to kill oneself to suicidal or depressed posters. The newsgroup was unmoderated and subject to a high level of trolling and a harsh and sometimes hostile atmosphere. According to its FAQ, its purpose is neither to encourage nor discourage suicide.
alt.sex is a Usenet newsgroup – a discussion group within the Usenet network – relating to human sexual activity. It was popular in the 1990s. An October 1993 survey by Brian Reid reported an estimated worldwide readership for the alt.sex newsgroup of 3.3 million, that being 8% of the total Usenet readership, with 67% of all Usenet "nodes" carrying the group. At that time, alt.sex had an estimated traffic of 2,300 messages per month.
Forté Agent is an email and Usenet news client used on the Windows operating system. Agent was conceived, designed and developed by Mark Sidell and the team at Forté Internet Software in 1994 to address the need for an online/offline newsreader which capitalized on the emerging Windows GUI framework. By 1995, Agent had expanded to become a full-featured email client and remains a widely used application for integrating news and email communication on Windows. Agent supports POP email but not IMAP.
alt.tv.simpsons is a usenet newsgroup dedicated to discussing the American television program The Simpsons. Created in 1990, the newsgroup became a popular community in the early 1990s, and continues to exist as of 2023. It is known for reviewing episodes and nitpicking minor details on the show.
talk.origins is a moderated Usenet discussion forum concerning the origins of life, and evolution. It remains a major venue for debate in the creation–evolution controversy, and its official purpose is to draw such debates out of the science newsgroups, such as sci.bio.evolution and sci.bio.paleontology.
alt.atheism is a Usenet newsgroup within the alt.* hierarchy that discusses atheism. The group was originally created on February 6, 1990 by a member of the alt.pagan newsgroup, to provide an alternative forum for the numerous discussions on atheism that were overwhelming the pagan group. A survey of usenet groups in 1994–1995 found that, among 70 groups discussing "consciousness, spirituality, and religion ", it was the group with the highest traffic volume. Nash (2002) writes that "atheist and freethought newsgroups" including alt.atheism have "done much to remove the sense of isolation felt by many with antireligious opinions".
Usenet II was a proposed alternative to the classic Usenet hierarchy, started in 1998. Unlike the original Usenet, it was peered only between "sound sites" and employed a system of rules to keep out spam.
rec.arts.sf.tv.babylon5.moderated is a moderated Usenet newsgroup that focuses on the science fiction television series Babylon 5 and the works of writer J. Michael Straczynski. It was spun off from its un-moderated version, rec.arts.sf.tv.babylon5, in 1996. The newsgroup counts Straczynski as a frequent contributor, and was among the first internet-based forums where fans interacted directly with a 'showrunner'.
The Big 8 are a group of newsgroup hierarchies established after the Great Renaming, a restructuring of Usenet that took place in 1987. These hierarchies are managed by the Big 8 Management Board. Groups are added through a process of nomination, discussion and voting.
Control messages are a special kind of Usenet post that are used to control news servers. They differ from ordinary posts by a header field named Control
. The body of the field contains control name and arguments.
A Usenet personality was a particular kind of Internet celebrity, being an individual who gained a certain level of notoriety from posting on Usenet, a global network of computer users with a vast array of topics for discussion. The platform is usually anonymous, although users can get celebrity status, usually by being deemed different from other posters in some way.
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.
The Meow Wars were an early example of a flame war sent over Usenet which began in 1996 and ended circa 1998. Its participants were known as "Meowers". The war was characterized by posters from one newsgroup "crapflooding", or posting a large volume of nonsense messages, to swamp on-topic communication in other groups. Ultimately, the flame war affected many boards, with Roisin Kiberd writing in Motherboard, a division of Vice, that esoteric Internet vocabulary was created as a result of the Meow Wars.
