The very first thing to clarify is that Usenet Newsgroups are not a part of any organization and do not have any centralized network management authority. This in itself makes it very distinct. Unlike the once popular peer-to-peer networks, Usenet is not a file-sharing program and has not only been around for far longer, but in and of itself works entirely different. It is easier define what Usenet is not versus what it truly is.
Some examples:

We are often asked: "What is Usenet?", "What are Usenet Newsgroups?", and "Where can I get Usenet newsgroup access?" Usenet is a worldwide system of discussion groups used by tens of millions of people on the internet today. Think of Usenet Newsgroups as a one-to-many teleconferencing system. The operation of Usenet is most similar to the way that the combination of e-mail AND forums work. Working much like an email/forum, a posted message/article gets posted publicly to a local group (AKA Newsgroups, which we’ll get to in a minute). With Usenet access, you can read and post messages (called “articles” or “posts”) at your own convenience. Allowing the user to follow these articles days, weeks and even months from the date it was posted with the ability to respond and read responses from these local groups.

Just reading articles/posts are not the only thing Usenet does. With hardly any restrictions on actual “space”, Usenet is extremely popular in being able to post enormous files to pass along to public domains. Universities find the most convenience with this as this allows them to post large size files to be shared within a community. As an example, imagine an online text-book on quantum physics. The file itself could exceed anywhere from 100-200mb in size! How would you go about sending the file to 100+ online students? E-mail would be entirely too slow, and chances are you’d get fired just for trying. Posting it on your University’s internet site would not only bog the site down, but is not feasible for a number of reasons. Solution: USENET!

With Usenet, all you would have to do is post it on an intended newsgroup, let your students know where to look, and they can download the file at there own convenience. Additionally, you can track if there are any responses and questions students potentially have. 

The articles and files on Usenet is divided into thousands of newsgroups. Each newsgroup is defined by a particular topic. From education to music to movies and even the meaning of life, Usenet newsgroups are a repository of information for anything you can possibly imagine.

Newsgroups are the general topics of Usenet. Although millions of them exist, only a few thousand are truly popular. “Popular” Usenet Newsgroups exchange virtually anything and everything you can imagine. ” From the studies of science to general discussions and postings of japanimation films, Newsgroups are a vital part of cyberspace communication as we know it.

Topics are by the millions with Newsgroups.  Everyday, these groups grow in size and popularity.  Most of the major newsgroups have what is called a “charter”. A Charter specifies the topics of discussion and assigns a moderator if there is a demand or if its necessary for the particular group. This is most prominent with usenet newsgroups that share a lot of articles and files, otherwise known as “posts”.

Here, the example is again made about sharing a large file amongst a public community. In this example, it could very well be a musician who wishes to share his collection of his work with the public. Rather than hosting the files on his own site, he can post these songs on a particular usenet newsgroup and not only have his files downloaded and played by this group, but respond about they’re thoughts on the music. This allows the musician to have instantaneous access to this group no matter where he or she is without any time restraints. The posts and its replies would reside on the newsgroup for weeks to months.

Consider newsgroups as a large bulletin board for the masses. They’re formed by groups of people swapping information on a variety of subjects.  Where users can share ideas, ask questions and share practically anything.

Until recently, ISP’s were known to give you unlimited, uncensored newsgroup access news servers as part of your internet access package. Nowadays more companies are dropping there newsgroup service due to the overwhelming costs it takes to maintain it. Couple that with the popularity Usenet has recently been having, and you can sympathize with there situation.

Even if you do have an ISP who does offer usenet newsgroup access or services, more often than not, they are limited. Imposing download caps on its users and offering a horrible retention rates (the amount of time the files stay on a server) and censoring its users. Because of this, Newsdemon was created. Newsdemon is a provider of usenet access which allows users to access the tens of thousands of newsgroups and news servers available today.

Newsdemon has a great retention rate (with files ranging from 65 days old to new) and is completely uncensored. With Newsdemon, you are able to access the world of newsgroups the way they are intended. To truly experience Usenet as it was intended, Newsdemon has unlimited packages for its members.

Be weary of very shady outfits on the internet today that sell Usenet service. There are many hosting providers currently out there. Only a handful that can be trusted.

Now that you know what about Usenet is and WHERE to get it, the question is, HOW do you access these Newsgroups?
Answer: Newsreaders

Newsreaders are software programs that continually search thousands of newsgroups for posts. A newsreader is capable of handling multiple usenet newsgroups to scan, read and download articles from a particular newsgroup. With a newsreader, you can easily access a newsgroup, post a message, and download anything and everything the newsgroup of interest has to offer.

As an example, let’s say there is a group called alt.education.research (which there is). With a newsreader, you would be able to view the full contents of the group. Imagine it’s like email again where you would see a full inbox of thousands of messages from users collaborating on a variety of different aspects of education research. With most newsreaders, you can scan these emails by topic, keywords or content. Allowing you to view, follow and/or download only the subject matters that interest you.

Many times, large files are broken up into smaller parts to allow the user to download easier. With some newsreaders, you can combine these files so you can make one swift download which you can combine later on. A great convenience for a lot of users.

Currently, there are hundreds of newsreaders to choose from. NewsRover, a very popular newsreader is one that Newsdemon recommends for its users. It’s ease of use and the way it handles usenet newsgroups become common tasks versus the tedious and advanced functions others provide.
