What is Newsgroup?

The name for a discussion group on USENET, or an electronic discussion group consisting of collections of related postings (also called articles) on a particular topic that are posted to a news server which then distributes them to other participating servers.

Newsgroups are classified by subject matter and do not necessarily deal with journalism or "news." Health, hobbies, celebrities, and cultural events are the subjects of many newsgroups. Participants in a newsgroup conduct discussions by posting messages for others to read, and responding to the messages posted by others.

Unlike a magazine or newspaper subscription, a subscription to a newsgroup is free.
