Usenet newsgroup

A Usenet newsgroup is a repository usually within the Usenet system, for messages posted from many users in different locations using Internet.

Users read and post messages (called articles or posts, and collectively termed news) to one or more categories, known as newsgroups.

Newsgroups are technically distinct from, but functionally similar to, discussion forums on the World Wide Web.

Early Internet forums could be described as a web version of an electronic mailing list or newsgroup (such as exist on Usenet); allowing people to post messages and comment on other messages.

Newsreader software is used to read the content of newsgroups.

A newsreader is an application program that reads articles on Usenet (a distributed discussion system, which groups its content into a hierarchy of subject-related newsgroups, each of which contains multiple threads or discussions).

They are discussion groups and are not devoted to publishing news.

People respond, add comments, and make posts on such forums, as well as on established mailing lists, in news groups, or in IRC channels.

Newsgroups are technically distinct from, but functionally similar to, discussion forums on the World Wide Web. Before the adoption of the World Wide Web, Usenet newsgroups were among the most popular Internet services, and have retained their noncommercial nature in contrast to the increasingly ad-laden web.

On 6 August 1991, Berners-Lee published a short summary of the World Wide Web project on the newsgroup alt.hypertext.

When replying to long discussions, particularly in newsgroup discussions, quoted text from the original message is often trimmed so as to leave only the parts that are relevant to the reply — or only a reminder thereof.

Some newsgroups allow posts on a wide variety of themes, regarding anything a member chooses to discuss as on-topic, while others keep more strictly to their particular subject, frowning on off-topic posts.

In the context of mailing lists, discussion groups, discussion forums, bulletin boards, newsgroups, and

The first is completion rates and the other is retention rates.

Completion rates measure the useful transmission of complete binary files across newsgroups.

The news admin (the administrator of a news server) decides how long posts are kept on their server before being expired (deleted).

To work around the problem, a redundancy scheme known as Parchive (PAR) is commonly used.

Parchive was intended to increase the reliability of transferring files via Usenet newsgroups.

These were all created in the Great Renaming of 1986–1987, before which all of these newsgroups were in the net.* hierarchy.

The Great Renaming was a restructuring of Usenet newsgroups that took place in 1987.

Among those that the Usenet cabal (who effectively ran the Big 7 at the time) did not allow were those concerning recipes, recreational drug use, and sex.

The backbone cabal was an informal organization of large-site administrators of the worldwide distributed newsgroup-based discussion system Usenet.

The alt.* hierarchy has discussion of all kinds of topics, and many hierarchies for discussion specific to a particular geographical area or in a language other than English.

The alt.* hierarchy is a major class of newsgroups in Usenet, containing all newsgroups whose name begins with "alt.", organized hierarchically.

The comp.* hierarchy is a major class of newsgroups in Usenet, containing all newsgroups whose name begins with "comp.", organized hierarchically.

The sci.* hierarchy is a major class of newsgroups in Usenet, containing all newsgroups whose name begins with "sci.", organized hierarchically.

For newsgroups that are not widely carried, sometimes a carrier group is used for crossposting to aid distribution.

Crossposting is the act of posting the same message to multiple information channels; forums, mailing lists, or newsgroups.

Programs called newsreaders are used to read and post messages (called articles or posts, and collectively termed news) to one or more newsgroups.

The first Internet Usenet newsgroup dedicated to cooking was net.cooks created in 1982, later becoming rec.food.cooking.

Communication is facilitated by the Network News Transfer Protocol (NNTP) which allows connection to Usenet servers and data transfer over the internet.

The resulting protocol was NNTP, which resembled the Simple Mail Transfer Protocol (SMTP) but was tailored for exchanging newsgroup articles.

In recent years, this form of open discussion on the Internet has lost considerable ground to individually-operated browser-accessible forums and big media social networks such as Facebook and Twitter.
