Usenet (),
a portmanteau of 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.

A major difference between a BBS or web message board and Usenet is the absence of a central server and dedicated administrator or hosting provider. Usenet is distributed among a large, constantly changing set of
news servers that
store and forward messages to one another via "news feeds". Individual users may read messages from and post to a local (or simply preferred) news server, which can be operated by anyone, and those posts will automatically be forwarded to any other news servers
peered with the local one, while the local server will receive any news its peers have that it currently lacks. This results in the automatic proliferation of content posted by any user on any server to any other user subscribed to the same newsgroups on other servers.
As with BBSes and message boards, individual news servers or service providers are under no obligation to carry any specific content, and may refuse to do so for many reasons: a news server might attempt to control the spread of spam by refusing to accept or forward any posts that trigger
spam filters, or a server without high-capacity data storage may refuse to carry any newsgroups used primarily for
file sharing

, limiting itself to discussion-oriented groups. However, unlike BBSes and web forums, the dispersed nature of Usenet usually permits users who are interested in receiving some content to access it simply by choosing to connect to news servers that carry the feeds they want.

news software such as
A News. The name "Usenet" emphasizes its creators' hope that the
USENIX organization would take an active role in its operation.
The articles that users post to Usenet are organized into topical categories known as
newsgroups
A Usenet newsgroup is a repository usually within the Usenet system for messages posted from users in different locations using the Internet. They are not only discussion groups or conversations, but also a repository to publish articles, start ...
, which are themselves logically organized into hierarchies of subjects. For instance, ''
ews:sci.math sci.math' and ''
ews:sci.physics sci.physics' are within the ''sci.*'' hierarchy. Or, ''
ews:talk.origins talk.origins' and ''
ews:talk.atheism talk.atheism' are in the ''talk.*'' hierarchy. When a user subscribes to a newsgroup, the
news client software keeps track of which articles that user has read.
In most newsgroups, the majority of the articles are responses to some other article. The set of articles that can be traced to one single non-reply article is called a
thread. Most modern newsreaders display the articles arranged into threads and subthreads. For example, in the wine-making newsgroup ''rec.crafts.winemaking,'' someone might start a thread called; "What's the best yeast?" and that thread or conversation might grow into dozens of replies long, by perhaps six or eight different authors. Over several days, that conversation about different wine yeasts might branch into several sub-threads in a tree-like form.
When a user posts an article, it is initially only available on that user's news server. Each news server talks to one or more other servers (its "newsfeeds") and
exchanges articles with them. In this fashion, the article is copied from
server to server and should eventually reach every server in the network. The later

networks operate on a similar principle, but for Usenet it is normally the sender, rather than the receiver, who initiates transfers. Usenet was designed under conditions when networks were much slower and not always available. Many sites on the original Usenet network would connect only once or twice a day to batch-transfer messages in and out. This is largely because the
POTS network was typically used for transfers, and phone charges were lower at night.
The format and transmission of Usenet articles is similar to that of Internet

ISPs, news servers, and newsfeeds

Many Internet service providers, and many other Internet sites, operate
news servers for their users to access. ISPs that do not operate their own servers directly will often offer their users an account from another provider that specifically operates newsfeeds. In early news implementations, the server and newsreader were a single program suite, running on the same system. Today, one uses separate newsreader client software, a program that resembles an email client but accesses Usenet servers instead.
Not all ISPs run news servers. A news server is one of the most difficult Internet services to administer because of the large amount of data involved, small customer base (compared to mainstream Internet service), and a disproportionately high volume of customer support incidents (frequently complaining of missing news articles). Some ISPs outsource news operations to specialist sites, which will usually appear to a user as though the ISP itself runs the server. Many of these sites carry a restricted newsfeed, with a limited number of newsgroups. Commonly omitted from such a newsfeed are foreign-language newsgroups and the ' hierarchy which largely carries software, music, videos and images, and accounts for over 99 percent of article data.
There are also Usenet providers that offer a full unrestricted service to users whose ISPs do not carry news, or that carry a restricted feed.
Newsreaders
Newsgroups are typically accessed with
newsreaders: applications that allow users to read and reply to postings in newsgroups. These applications act as
clients to one or more news servers. Historically, Usenet was associated with the

, but newsreaders were soon available for all major operating systems. Email client programs and
Internet suites of the late 1990s and 2000s often included an integrated newsreader. Newsgroup enthusiasts often criticized these as inferior to standalone newsreaders that made correct use of Usenet protocols, standards and conventions.
With the rise of the World Wide Web (WWW), web front-ends (web2news) have become more common. Web front ends have lowered the technical entry barrier requirements to that of one application and no Usenet NNTP server account. There are numerous websites now offering web based gateways to Usenet groups, although some people have begun filtering messages made by some of the web interfaces for one reason or another.
Google Groups is one such web based front end and some

Moderated and unmoderated newsgroups
A minority of newsgroups are moderated, meaning that messages submitted by readers are not distributed directly to Usenet, but instead are emailed to the moderators of the newsgroup for approval. The moderator is to receive submitted articles, review them, and inject approved articles so that they can be properly propagated worldwide. Articles approved by a moderator must bear the Approved: header line. Moderators ensure that the messages that readers see in the newsgroup conform to the charter of the newsgroup, though they are not required to follow any such rules or guidelines. Typically, moderators are appointed in the proposal for the newsgroup, and changes of moderators follow a succession plan.
Historically, a ''mod.*'' hierarchy existed before Usenet reorganization. Now, moderated newsgroups may appear in any hierarchy, typically with
.moderated
added to the group name.
Usenet newsgroups in the
Big-8 hierarchy are created by proposals called a Request for Discussion, or RFD. The RFD is required to have the following information: newsgroup name, checkgroups file entry, and moderated or unmoderated status. If the group is to be moderated, then at least one moderator with a valid email address must be provided. Other information which is beneficial but not required includes: a charter, a rationale, and a moderation policy if the group is to be moderated. Discussion of the new newsgroup proposal follows, and is finished with the members of the Big-8 Management Board making the decision, by vote, to either approve or disapprove the new newsgroup.
Unmoderated newsgroups form the majority of Usenet newsgroups, and messages submitted by readers for unmoderated newsgroups are immediately propagated for everyone to see. Minimal editorial content filtering vs propagation speed form one crux of the Usenet community. One little cited defense of propagation is canceling a propagated message, but few Usenet users use this command and some news readers do not offer
cancellation commands, in part because article storage expires in relatively short order anyway. Almost all unmoderated Usenet groups tend to receive large amounts of

Technical details
Usenet is a set of protocols for generating, storing and retrieving news "articles" (which resemble Internet mail messages) and for exchanging them among a readership which is potentially widely distributed. These protocols most commonly use a
flooding algorithm which propagates copies throughout a network of participating servers. Whenever a message reaches a server, that server forwards the message to all its network neighbors that haven't yet seen the article. Only one copy of a message is stored per server, and each server makes it available on demand to the (typically local) readers able to access that server. The collection of Usenet servers has thus a certain
peer-to-peer
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network, forming a peer-to-peer network of Node ...
character in that they share resources by exchanging them, the granularity of exchange however is on a different scale than a modern peer-to-peer system and this characteristic excludes the actual users of the system who connect to the news servers with a typical client-server application, much like an email reader.
RFC 850 was the first formal specification of the messages exchanged by Usenet servers. It was superseded by RFC 1036 and subsequently by RFC 5536 and RFC 5537.
In cases where unsuitable content has been posted, Usenet has support for automated removal of a posting from the whole network by creating a cancel message, although due to a lack of authentication and resultant abuse, this capability is frequently disabled. Copyright holders may still request the manual deletion of infringing material using the provisions of

Organization

The major set of worldwide newsgroups is contained within nine hierarchies, eight of which are operated under consensual guidelines that govern their administration and naming. The current ''
Big Eight'' are:
* ''comp.*'' – computer-related discussions (''comp.software'', ''comp.sys.amiga'')
* ''humanities.*'' –

(''humanities.classics'', ''humanities.design.misc'')
* ''misc.*'' – miscellaneous topics (''misc.education'', ''misc.forsale'', ''misc.kids'')
* ''news.*'' – discussions and announcements about news (meaning Usenet, not current events) (''news.groups'', ''news.admin'')
* ''rec.*'' – recreation and entertainment (''rec.music'', ''rec.arts.movies'')
* ''sci.*'' – science related discussions (''sci.psychology'', ''sci.research'')
* ''soc.*'' – social discussions (''soc.college.org'', ''soc.culture.'')
* ''talk.*'' – talk about various controversial topics (''talk.religion'', ''talk.politics'', ''
talk.origins'')
The
''alt.*'' hierarchy is not subject to the procedures controlling groups in the Big Eight, and it is as a result less organized. Groups in the ''alt.*'' hierarchy tend to be more specialized or specific—for example, there might be a newsgroup under the Big Eight which contains discussions about children's books, but a group in the alt hierarchy may be dedicated to one specific author of children's books.
Binaries are posted in ', making it the largest of all the hierarchies.
Many other hierarchies of newsgroups are distributed alongside these. Regional and language-specific hierarchies such as ''.*'', ''.*'' and ''ne.*'' serve specific countries and regions such as

Some users prefer to use the term "Usenet" to refer only to the Big Eight hierarchies; others include ''alt.*'' as well. The more general term "netnews" incorporates the entire medium, including private organizational news systems.
Informal sub-hierarchy conventions also exist. ''*.answers'' are typically moderated cross-post groups for FAQs. An FAQ would be posted within one group and a cross post to the ''*.answers'' group at the head of the hierarchy seen by some as a refining of information in that news group. Some subgroups are recursive—to the point of some silliness in ''alt.*''.
Binary content

Usenet was originally created to distribute text content encoded in the 7-
bit ASCII
ASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English language focused) printable character, printable and 33 control character, control c ...

s as content. Binary posts, due to their size and often-dubious copyright status, were in time restricted to specific newsgroups, making it easier for administrators to allow or disallow the traffic.
The oldest widely used encoding method for binary content is

XX encoding,
BOO, and USR encoding.
In an attempt to reduce file transfer times, an informal file encoding known as
yEnc was introduced in 2001. It achieves about a 30% reduction in data transferred by assuming that most 8-bit characters can safely be transferred across the network without first encoding into the 7-bit ASCII space. The most common method of uploading large binary posts to Usenet is to convert the files into
RAR archives and create
Parchive files for them. Parity files are used to recreate missing data when not every part of the files reaches a server.

Binary retention time

Each news server allocates a certain amount of storage space for content in each newsgroup. When this storage has been filled, each time a new post arrives, old posts are deleted to make room for the new content. If the network bandwidth available to a server is high but the storage allocation is small, it is possible for a huge flood of incoming content to overflow the allocation and push out everything that was in the group before it. The average length of time that posts are able to stay on the server before being deleted is commonly called the ''retention time''.
Binary newsgroups are only able to function reliably if there is sufficient storage allocated to handle the amount of articles being added. Without sufficient retention time, a reader will be unable to download all parts of the binary before it is flushed out of the group's storage allocation. This was at one time how posting undesired content was countered; the newsgroup would be flooded with random garbage data posts, of sufficient quantity to push out all the content to be suppressed. This has been compensated by service providers allocating enough storage to retain everything posted each day, including spam floods, without deleting anything.
Modern Usenet
news servers have enough capacity to archive years of binary content even when flooded with new data at the maximum daily speed available.
In part because of such long retention times, as well as growing Internet

data. While commercial providers offer easier to use
online backup services, storing data on Usenet is free of charge (although access to Usenet itself may not be). The method requires the uploader to cede control over the distribution of the data; the files are automatically disseminated to all Usenet providers exchanging data for the news group it is posted to. In general the user must manually select, prepare and upload the data. The data is typically
encrypted because it is available to anyone to download the backup files. After the files are uploaded, having multiple copies spread to different geographical regions around the world on different
news servers decreases the chances of data loss.
Major Usenet service providers have a retention time of more than 12 years. This results in more than 60
petabytes (60000
terabytes) of storage (see image). When using Usenet for data storage, providers that offer longer retention time are preferred to ensure the data will survive for longer periods of time compared to services with lower retention time.
Legal issues

, copyrighted media, and pornographic material.
ISP-operated Usenet servers frequently block access to all ' groups to both reduce network traffic and to avoid related legal issues. Commercial Usenet service providers claim to operate as a telecommunications service, and assert that they are not responsible for the user-posted binary content transferred via their equipment. In the United States, Usenet providers can qualify for protection under the
DMCA Safe Harbor regulations, provided that they establish a mechanism to comply with and respond to takedown notices from copyright holders.
Removal of copyrighted content from the entire Usenet network is a nearly impossible task, due to the rapid propagation between servers and the retention done by each server. Petitioning a Usenet provider for removal only removes it from that one server's retention cache, but not any others. It is possible for a special ''post cancellation'' message to be distributed to remove it from all servers, but many providers ignore
cancel messages by standard policy, because they can be easily falsified and submitted by anyone. For a takedown petition to be most effective across the whole network, it would have to be issued to the origin server to which the content has been posted, before it has been propagated to other servers. Removal of the content at this early stage would prevent further propagation, but with modern high speed links, content can be propagated as fast as it arrives, allowing no time for content review and takedown issuance by copyright holders.
Establishing the identity of the person posting illegal content is equally difficult due to the trust-based design of the network. Like
SMTP
The Simple Mail Transfer Protocol (SMTP) is an Internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages. User-level email clients typi ...
email, servers generally assume the header and origin information in a post is true and accurate. However, as in SMTP email, Usenet post headers are easily falsified so as to obscure the true identity and location of the message source. In this manner, Usenet is significantly different from modern P2P services; most P2P users distributing content are typically immediately identifiable to all other users by their
network address, but the origin information for a Usenet posting can be completely obscured and unobtainable once it has propagated past the original server.
Also unlike modern P2P services, the identity of the downloaders is hidden from view. On P2P services a downloader is identifiable to all others by their network address. On Usenet, the downloader connects directly to a server, and only the server knows the address of who is connecting to it. Some Usenet providers do keep usage logs, but not all make this logged information casually available to outside parties such as the

connections. By 1983, thousands of people participated from more than 500 hosts, mostly universities and Bell Labs sites but also a growing number of Unix-related companies; the number of hosts nearly doubled to 940 in 1984. More than 100 newsgroups existed, more than 20 devoted to Unix and other computer-related topics, and at least a third to recreation. As the mesh of UUCP hosts rapidly expanded, it became desirable to distinguish the Usenet subset from the overall network. A vote was taken at the 1982 USENIX conference to choose a new name. The name Usenet was retained, but it was established that it only applied to news. The name UUCPNET became the common name for the overall network.
In addition to UUCP, early Usenet traffic was also exchanged with
FidoNet and other dial-up
BBS networks. By the mid-1990s there were almost 40,000 FidoNet systems in operation, and it was possible to communicate with millions of users around the world, with only local telephone service. Widespread use of Usenet by the BBS community was facilitated by the introduction of UUCP feeds made possible by MS-DOS implementations of UUCP, such as UFGATE (UUCP to FidoNet Gateway), FSUUCP and UUPC. In 1986, RFC 977 provided the
Network News Transfer Protocol (NNTP) specification for distribution of Usenet articles over
TCP/IP
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are ...
as a more flexible alternative to informal Internet transfers of UUCP traffic. Since the Internet boom of the 1990s, almost all Usenet distribution is over NNTP.
Software
Early versions of Usenet used Duke's
A News software, designed for one or two articles a day. Matt Glickman and Horton at Berkeley produced an improved version called
B News that could handle the rising traffic (about 50 articles a day as of late 1983). With a message format that offered compatibility with Internet mail and improved performance, it became the dominant server software.

, was comparable to B News in features but offered considerably faster processing. In the early 1990s,
InterNetNews by
Rich Salz was developed to take advantage of the continuous message flow made possible by NNTP versus the batched store-and-forward design of UUCP. Since that time
INN development has continued, and other news server software has also been developed.

disk space and traffic increased correspondingly. Internet service providers questioned why they needed to host binary articles.
AOL discontinued Usenet access in 2005. In May 2010,

will live on". While there are still some active text newsgroups on Usenet, the system is now primarily used to share large files between users, and the underlying technology of Usenet remains unchanged.
Usenet traffic changes
Over time, the amount of Usenet traffic has steadily increased. the number of all text posts made in all Big-8 newsgroups averaged 1,800 new messages every hour, with an average of 25,000 messages per day.
However, these averages are minuscule in comparison to the traffic in the binary groups. Much of this traffic increase reflects not an increase in discrete users or newsgroup discussions, but instead the combination of massive automated spamming and an increase in the use of ' newsgroups
in which large files are often posted publicly. A small sampling of the change (measured in feed size per day) follows:

. Time Warner Cable stopped offering access to Usenet. Verizon reduced its access to the "Big 8" hierarchies. Sprint stopped access to the ''alt.*'' hierarchies. AT&T stopped access to the ' hierarchies. Cuomo never specifically named Usenet in his anti-child pornography campaign. David DeJean of ''
PC World'' said that some worry that the ISPs used Cuomo's campaign as an excuse to end portions of Usenet access, as it is costly for the Internet service providers and not in high demand by customers. In 2008
AOL, which no longer offered Usenet access, and the four providers that responded to the Cuomo campaign were the five largest Internet service providers in the United States; they had more than 50% of the U.S. ISP market share.

AOL announced that it would discontinue its integrated Usenet service in early 2005, citing the growing popularity of weblogs, chat forums and on-line conferencing. The AOL community had a tremendous role in popularizing Usenet some 11 years earlier.

s, along with cost and liability concerns of increasing proportion of traffic devoted to file-sharing and spam on unused or discontinued groups.
Some ISPs did not include pressure from Cuomo's campaign against child pornography as one of their reasons for dropping Usenet feeds as part of their services. ISPs Cox and Atlantic Communications resisted the 2008 trend but both did eventually drop their respective Usenet feeds in 2010.
Archives
Public archives of Usenet articles have existed since the early days of Usenet, such as the system created by Kenneth Almquist in late 1982. Distributed archiving of Usenet posts was suggested in November 1982 by Scott Orshan, who proposed that "Every site should keep all the articles it posted, forever." Also in November of that year,
Rick Adams responded to a post asking "Has anyone archived netnews, or does anyone plan to?" by stating that he was, "afraid to admit it, but I started archiving most 'useful' newsgroups as of September 18." In June 1982, Gregory G. Woodbury proposed an "automatic access to archives" system that consisted of "automatic answering of fixed-format messages to a special mail recipient on specified machines."
In 1985, two news archiving systems and one
RFC were posted to the Internet. The first system, called keepnews, by Mark M. Swenson of the

, was described as "a program that attempts to provide a sane way of extracting and keeping information that comes over Usenet." The main advantage of this system was to allow users to mark articles as worthwhile to retain. The second system, YA News Archiver by Chuq Von Rospach, was similar to keepnews, but was "designed to work with much larger archives where the wonderful quadratic search time feature of the Unix ... becomes a real problem." Von Rospach in early 1985 posted a detailed RFC for "archiving and accessing usenet articles with
keyword lookup." This RFC described a program that could "generate and
maintain an archive of Usenet articles and allow looking up articles based on the article-id, subject lines, or keywords pulled out of the article itself." Also included was
C code for the internal data structure of the system.
The desire to have a full text search index of archived news articles is not new either, one such request having been made in April 1991 by
Alex Martelli who sought to "build some sort of keyword index for
he news archive" In early May, Martelli posted a summary of his responses to Usenet, noting that the "most popular suggestion award must definitely go to 'lq-text' package, by Liam Quin, recently posted in alt.sources."
The Alt Sex Stories Text Repository (ASSTR) site archived and indexed erotic and pornographic stories posted to the Usenet group
alt.sex.stories.
The archiving of Usenet has led to fears of loss of privacy. An archive simplifies ways to profile people. This has partly been countered with the introduction of the ''
X-No-Archive: Yes'' header, which is itself controversial.
Archives by Google Groups and Deja News
Web-based archiving of Usenet posts began in March 1995 at
