What Is a Newsgroup?
A newsgroup is a public discussion group on Usenet devoted to one topic. There are groups for astronomy, cooking, programming, classic cars, family history and thousands of other subjects, and anyone with a Usenet account and a newsreader app can read them.
A newsgroup isn’t a website. Its posts are copied between news servers around the world, so you read it on your own provider’s server, and your replies reach readers on other servers too. Our overview explains how Usenet works. No single company owns a newsgroup, and you don’t visit a particular site to take part.
Articles, threads and replies
Each message in a newsgroup is called an article. When someone answers an article, the reply is linked to it, so your newsreader can show the whole conversation as a thread, one reply under another. You can follow the threads that interest you, skip the rest, and mark a whole thread as read when you’re done with it.
Subscribing doesn’t mean signing up
To follow a group, you subscribe to it in your newsreader. That only tells the app which groups to show and check for new posts. There’s no separate account for each group, nobody in the group is told, and you can unsubscribe at any time with a click.
Key takeaway
A newsgroup is a public conversation about one topic, shared across servers worldwide. Subscribing simply adds it to your newsreader, with no sign-up for each group.
Discussion Groups and File Groups
Most newsgroups are discussion groups, including all but one of the official Big-8 groups. Their posts are plain text: questions and answers, news, advice and debate, much like a forum.
Other groups are made for files. Usenet was built for text, so a file is converted into text and split across many articles, which your newsreader downloads and puts back together. These are called binary groups, and their names usually include the word “binaries”. People use them to share files they have the right to share, such as their own work, open-source software and public-domain material. Our guide to files explains how files travel on Usenet.
The two kinds call for different tools:
- Discussion groups: a text newsreader such as Thunderbird or Pan, made for reading threads and replying.
- File groups: a downloader such as SABnzbd or NZBGet, which usually works from an NZB file.
- Both: GrabIt for Windows, which Fast Usenet members get with search included.
Our newsreaders page compares them. One rule of thumb: don’t post files to discussion groups. It’s considered bad manners, and readers there don’t want to download them.
Back to contentsModerated Newsgroups, Charters and FAQs
In most newsgroups, a post appears as soon as it reaches the server and then spreads to the others. A moderated group adds one step: your post goes to the group’s moderator first, and it appears only once they approve it. Moderators are usually volunteers who keep the group on topic and free of spam.
Moderation applies only to that one group. In the official Big-8 list from October 2026, 98 of the 1,897 groups are moderated, and the list marks them “Moderated”. Examples include news.answers and news.newusers.questions, a group for newcomers’ questions about Usenet. Many topics have both kinds: comp.os.linux.announce carries moderated announcements, while comp.os.linux.misc is open discussion.
Learn moreHow moderation works behind the scenes
Your newsreader posts as usual, but the server doesn’t publish the article. It forwards it to the moderator instead, customarily by email, as the standard for how articles travel between servers (RFC 5537) describes. When the moderator approves it, they post it with an Approved line in its header, and from then on it spreads to other servers like any other article.
Charters and FAQs
Many groups have a charter, a short statement of what the group is for, and some have a FAQ: answers to the questions newcomers ask most often. FAQs are posted in their group from time to time, and many have also been posted to news.answers, the moderated group that collects them. Reading a group’s FAQ before you post is the quickest way to fit in.
How Newsgroups Are Named and Created
A newsgroup’s name reads from the general to the specific, with dots in between. The first part is its hierarchy: the Big 8 (comp, humanities, misc, news, rec, sci, soc and talk), the alt.* hierarchy, and regional and language hierarchies such as de.* for German and uk.* for the United Kingdom. Our overview shows how a name breaks down, and our guide to newsgroup hierarchies tours every one of them.
How new newsgroups are created
Big-8 groups follow a public process. A proposal is announced in news.announce.newgroups and discussed in news.groups.proposals, and the Big-8 Management Board decides whether to create the group. You may come across older guides that describe public votes run by volunteer vote-takers; today the Board makes the decision. Groups in alt.* are created with far fewer formalities, and each provider decides which of them to carry.
How to Find Newsgroups on Any Topic
With more than 120,000 groups on our servers, a few simple searches go a long way:
- Search your newsreader’s group list. The first time you connect, your newsreader downloads the list of groups on the server. Type a keyword such as “astro” or “linux” to narrow it down.
- Use our newsgroup search to check whether Fast Usenet carries a group, before or after you sign up.
- Browse the official Big-8 list, which gives every Big-8 group with a one-line description.
- Follow the conversation. Group FAQs and regular posters often point to related groups.
Popular topics and where to find them
| Topic | Example group | What it covers |
|---|---|---|
| Astronomy | sci.astro.amateur | Telescopes, techniques and observing |

Example: Linux newsgroups
Linux has close ties to Usenet: Linus Torvalds announced the project in a newsgroup in 1991, and the comp.os.linux.* groups still cover it from every angle:
comp.os.linux.miscfor general Linux topicscomp.os.linux.setupfor installation and system administrationcomp.os.linux.networkingfor networking under Linuxcomp.os.linux.hardwarefor hardware compatibilitycomp.os.linux.advocacyfor debate about Linux and other systemscomp.os.linux.announcefor moderated announcements
Example: car newsgroups
Car enthusiasts have a whole family of groups under rec.autos.*, including:
rec.autos.techfor technical questionsrec.autos.drivingfor drivingrec.autos.antiquefor cars more than 25 years oldrec.autos.makers.ford.mustangfor Ford Mustangsrec.autos.sport.f1for Formula 1 racingrec.autos.marketplacefor buying, selling and trading cars and parts
Example: game newsgroups
Gamers have groups for today’s consoles and retro systems alike, plus groups where hobbyists design and build their own games:
rec.games.video.nintendofor Nintendo consoles and gamesrec.games.video.sonyfor PlayStation hardware and gamesrec.games.video.miscfor home video games in general, today’s consoles includedrec.games.video.classicfor older home consolesrec.games.computer.doom.editingfor building your own Doom levels and modsrec.games.int-fictionfor interactive fiction (text adventure) gamesrec.games.designfor game design
Usenet is also a handy way to share files you’re free to pass on, such as homebrew games, fan-made levels and free, open-source games. Our guide to how files travel on Usenet explains how it works.
Example: cartoon and animation newsgroups
Animation fans and artists have their own corner of rec.arts.*:
rec.arts.animationfor all kinds of animationrec.arts.anime.miscfor Japanese animationrec.arts.anime.creativefor fans’ own original work (moderated)rec.arts.comics.miscfor comic books and graphic novelsrec.arts.comics.stripsfor comic strips
Independent animators can share their own films on Usenet too, much like posting a video online, and classic cartoons that are now in the public domain can be shared freely.
Example: photography newsgroups
Photographers of every level meet in rec.photo.*:
rec.photo.digitalfor digital cameras, scanners, printers and softwarerec.photo.digital.slr-systemsfor digital SLR camerasrec.photo.moderatedfor the art and science of photography (moderated)rec.photo.darkroomfor developing and printing filmrec.photo.marketplacefor buying and selling your own camera gear
Groups like these are for conversation. To share your own photos, use a group meant for files, as explained in discussion groups and file groups above.
Is the group still active?
Activity varies a lot from group to group. Some still see new posts every day, while others have gone quiet. Before you post, check the dates of the newest articles. Even a quiet group can be worth reading: with 6,654 days of retention, Fast Usenet keeps about 18 years of past discussion.
Key takeaway
Search your newsreader’s group list by keyword, check our newsgroup search, and look at the dates of recent posts to see how lively a group is.
How to Read and Join a Newsgroup
- Set up a newsreader with your Usenet account. Our overview has the settings, and our tutorials walk through each app.
- Subscribe to a few groups from the group list. Start small: you can always add more.
- Read before you post. Spend some time reading the group, often called lurking, and read its FAQ if it has one.
- Try a test post in
misc.testfirst. At Fast Usenet, posting is switched on by request to prevent abuse, so contact our support team and we’ll enable it for your account. - Answer in the right place. A follow-up posts your answer in the group for everyone to read, while a reply emails the author privately.
Newsgroups are public, so whatever name and email address you put in your newsreader appear on your posts. Many people use a nickname. Our guide to posting and netiquette covers good manners in more detail, and if you have a question about Usenet itself, news.newusers.questions is a moderated group made for newcomers.
Frequently Asked Questions
How many newsgroups are there?
No single list covers them all, because each provider carries its own selection. The official Big-8 list has 1,897 groups, and Fast Usenet carries more than 120,000 newsgroups across all hierarchies. Our newsgroup search shows whether we carry a group.
Do I need an account for each newsgroup?
No. One Usenet account gives you every group your provider carries. Subscribing to a group only adds it to your newsreader’s list.
Can I read newsgroups without posting?
Yes. Many people only read. You can follow any group without ever posting, and at Fast Usenet posting stays off until you ask us to switch it on.
What does “moderated” mean?
A moderator approves each post before it appears in the group, which keeps the group on topic and free of spam. Most groups are unmoderated, so posts appear straight away.
Are newsgroups still active?
Activity varies. Some groups still have new posts every day, while others have gone quiet. The dates of the newest articles show you which is which, and older posts stay readable for as long as your provider’s retention allows.
Can I create my own newsgroup?
Big-8 groups are created through a public proposal that the Big-8 Management Board approves. Groups in alt.* need fewer formalities, but each provider decides whether to carry a new group.
Is a newsgroup the same as a forum?
They feel similar, but a forum lives on one website, while a newsgroup is copied across news servers worldwide and read with a newsreader app. No single company owns it.
