The History Of Usenet - An Evolution Over Three Decades

The history of Usenet dates back to the late 1970’s, when two graduate students decided to put the world together to spark discussions and debates on a range of issues and share files from around the world, an idea sparked by Tom Truscott and Jim Ellis.

The history of Usenet started with the setting up of three small computers connected together to form a network, with the idea that they could use UUCP to get the machines connected to facilitate information exchange among users. The first mode of communication was facilitated through shell scripts, which were later to be rewritten in C, handling the small volume of traffic involved. The initial network was never made public, before they were replaced with the news software that powered the inception of “A” news – a software that was meant for information sharing and transfer of articles from one computer system to the other. However, the beginnings were humble, as always, with the sharing of just a few articles taking place among groups in any particular day. 

As this software became an effective tool towards sharing of information and as traffic volumes continued to grow, Mark Horton and Matt Glickman pitched in to take the file sharing software to the next level, with the release of the “B” release – the release was initially termed “B” news, with the advance in technology indicated from “A” to “B”. It was in 1982 that B News became a public version – and it has, since then, been expanding exponentially, with the introduction of new features and with software enhancements and releases.

It was 1987 when Geoff Collyer and Henry Spencer decided to give the software a facelift, with the upgrade to “C” News, or C-News. And, as always with the software world, there have been new features, releases and patches that have been constantly added – the most prominent of those new releases has been C-News Performance Release. By then, Usenet technology had become sophisticated enough to be able to handle traffic involving large number of groups, with ‘Relaynews’ gearing up to dispatch articles from one host to the other. While most news releases have been focussing on UUCP networks, with the introduction of “Network News transfer protocol” (NNTP) being introduced in 1986, they could well be used in other environments too, with news transfers taking place over networks that use other protocols such as TCP/IP or DECNet and such, to help in the transfer of articles over networks. NNTP-based applications provide for sharing of newsreading services among a number of hosts within a local network.

While many Universities and organisations have discontinued and de-commissioned usenet, there are, and will be, a loyal group of internet users who have been able to get the most mileage out of Usenet on NNTP.

How Usenet Works

The Usenet system has no centralized form of authority, meaning that there is no way rules can be enforced on those using the program. The main functions of the system are made possible and manageable through the cooperation of the managers of the news servers. The news server normally connects with other servers and at regular intervals files are passed from one place to another, allowing worldwide distribution.

Upon completion of an article using a particular newsgroup which is a discussion group, you will use your newsreader to pass the message to the new server. This article will then be distributed to other news servers within minutes or hours and at the same time you will find that your server will also receive articles from other servers within the system. The main procedure at work here is that the articles will be moving back and forth from one server to another, allowing discussions and files to be shared within a short period of time.

New articles are passed from one server to another until they eventually are propagated worldwide. The articles come with very unique identification codes to ensure that no server receives the same articles more than once. This has made it possible for the system to be synchronized and the most time an article can take to go around the world is probably a period of only two days, thanks to the internet.

The system organization is what makes it possible to manage the system without even having centralized management. The administration of the system imitates how the internet itself works in that there is no single person who can be said to be in charge of it as there are many different news servers involved, which would make management by an individual a difficult affair.

With Usenet, it is now possible to pass your messages along and even get to share files with people from any part of the world within a fairly short period of time. Most people have turned to the system, especially those who have pressing issues and need to spread them out to the world to obtain different opinions from different people from different parts of the world. The system has not only made it easy and fun to discuss issues with others but has also played a social networking aspect in the lives of the people who have taken the time to use the system.
