The Social Forces Behind the Development of Usenet

Right at this moment, somewhere in the world, someone is being helpful (or someone is being helped). At the same time, others are participating in online discussions and debates. A new communications medium is currently in its infancy. Over the past two decades a global computer telecommunications network has been developing. One element of this network is called Usenet (also known as Netnews). The original carrier of this news was called UUCPnet (or just UUCP).

The basic element of Usenet is a post. Each individual post consists of a unique contribution from a user, placed in a subject area called a newsgroup. In Usenet's beginning (and still to some extent today), posts were transferred using the UUCP utility distributed with Unix. This utility allows the use of phone lines to transmit computer data among separate computers.

Usenet grew from the ground up in a grassroots manner. Originally, there was no official structure. What began as two or three sites on the network in 1979 expanded to 15 in 1980, to 150 in 1981, to 400 in 1982. The very nature of Usenet is communication. Usenet greatly facilitates inter-human communication among a large group of users. The rawest principle of Usenet is its importance. In its simplest form, Usenet represents democracy.

Inherent in most mass media is central control of content. Many people are influenced by the decisions of a few. Television programming, for example, is controlled by a small group of people compared to the size of the audience. The audience has very little choice over what is emphasized by most mass media. Usenet, however, is controlled by its audience. Usenet should be seen as a promising successor to other people's presses, such as broadsides at the time of the American Revolution and the penny presses in England at the turn of the nineteenth century. Most of the material written to Usenet is contributed by the same people who actively read Usenet. Thus, the audience of Usenet decides the content and subject matter to be thought about, presented, and debated. The ideas that exist on Usenet come from the mass of people who participate in it. In this way, Usenet is an uncensored forum for debate where many sides of an issue come into view. Instead of being force-fed by an uncontrollable source of information, the participants set the tone and emphasis on Usenet. People control what happens on Usenet. In this rare situation, issues and concerns that are of interest, and thus important to the participants, are brought up. In the tradition of amateur radio and Citizen's Band radio, Usenet is the product of the users' ideas and will. Amateur radio and CB, however, are more restricted than Usenet. The range of Usenet connectivity is international and quickly expanding into every nook and cranny around the world. This explosive expansion allows growing communication among people around the world.

In the 1960s, the Advanced Research Projects Agency (ARPA) of the Department of Defense funded research of fundamental importance to the development and testing of computer communications networks. ARPA sponsored research laid the groundwork for the development of other net works such as UUCPnet. ARPA funded an experiment to attempt to connect incompatible mainframe computers [1]. This experimental connection of computers was called the ARPA Computer Network or the ARPANET. ARPA's stated objectives were:

1. To develop techniques and obtain experience on interconnecting computers in such a way that a very broad class of interactions were possible and

2. To improve and increase computer research productivity through resource sharing [2].

ARPA was sponsoring both communications research and the study of how to conserve funds by avoiding duplication of computer resources [ 3]. Bolt Beranek and Newman (BBN), a Cambridge, Massachusetts company, was chosen to construct the IMP subnetwork, and AT&T was chosen to provide the communications lines. The ARPANET was needed because it was found that a data connection over existing telephone voice lines was too slow and not reliable enough to make a useful connection [4]. Packet switching was developed for use as the protocol for exchanging information over the lines. Packet switching is a communications process in which all messages are broken up into small data packets which are transmitted interspersed and reassembled. In this way, short, medium and long messages get transferred with minimum delay [5].

The ARPANET was a success. It contributed several advances to communications research. ARPANET researchers were surprised at the enthusiastic adoption of electronic mail (e-mail) as the primary source of communication early on. E-mail was a source of increased productivity through the use of the ARPANET [6]. By 1983, the ARPANET officially shifted from using NCP (Network Control Program) to TCP/IP (Transmission Control Protocol/Internet Protocol.) A key part of TCP/IP's success lies in its simplicity. It is easy to implement over various platforms, and this simplicity has accounted for its continued existence as a defacto Internet standard up to the present. The ARPANET's lasting contribution was demonstrating how a backbone infrastructure can serve as a connection between gateways. A gateway is a computer or part of a computer programmed to receive messages from one network and transfer them onto another network.

The ARPANET quickly grew to more than 50 nodes between Hawaii and Norway [7]. However, it did not extend to all who could utilize it. Computer scientists at universities without Department of Defense contracts noticed the advantages and petitioned the National Science Foundation (NSF) for similar connectivity. CSnet was formed to service these computer scientists. CSnet was initially financed by the NSF. Very quickly, the desire for interconnection spread to other members of the university community. Soon CSnet grew to serve other scientists in addition to computer scientists at universities and came to mean "Computer and Science Network" rather than just "Computer Science Network" [8].

By the mid-1980s, the ARPANET was phased out by the Department of Defense and was replaced by various internal networks (such as MILNET). The role of connecting university communities and regional networks was taken over by the NSF-funded NSFnet, which originated as a connection for university researchers to the five National Supercomputer Centers. CSnet and NSFnet were made possible by the research on the ARPANET. The NSFnet became the U.S. backbone for the global network known as the Internet.

ARPANET research was pioneering communications research [9]. Researchers discovered the link between computer interconnection and increased productivity from human communication. The sharing of resources was proven as a way to save money and to increase computer use and productivity. The development of packet switching revolutionized the basic methodology of connecting computers.

The source of these discoveries were the people involved. The people involved in the ARPANET project were very intelligent and forward looking. They recognized that they were developing future technologies, and thus did not develop products that commercial industry could (and would) develop. Instead, they understood that the communications technologies they were developing had to come from a not-for-profit body. ARPA researchers had no proprietary products to support and no commercial deadlines to meet. Either requirement would have made developing networks of incompatible computers impossible or limited. Current users of international computer networks are in debt to the pioneers of the ARPANET.

The ARPANET was successful in its attempt to connect various spatially remote computers, and, thus, more importantly, the people who used those computers. However, these people were either professors at universities with Department of Defense research contracts or employees of a limited number of defense industry companies. There were still many people who wanted a connection but were not in a position to gain one. Duke University and the University of North Carolina at Chapel Hill were two such locations. In these underprivileged fertile grounds the grassroots computer communications breakthrough, Usenet, originated and developed.

The Unix operating system provides the basic tools needed to share information between computers. Unix [10] was developed as "a system around which a fellowship would form" [11]. One of the programmers of Unix, Dennis Ritchie, wrote that the intended purpose of Unix was to "encourage close communication" [12]. Unix's general principles thus conceptually foreshadowed the basic tenet of Usenet. How else should one go about designing communications programs but on an operating system designed with the basic principle of encouraging communication? The Unix utility UUCP was created at Bell Labs in 1976 by Mike Lesk. It was further developed by David Nowitz and later by Nowitz, Peter Honeyman, and Brian E. Redman. UUCP provided a simple way of passing files between any two computers running Unix and UUCP. One of AT&T's motivations in developing Unix was to make software production cheaper in order to bring down the cost of telephone service. Unix's popularity also arose from AT&T's prohibition from profiting from sources other than its main business, phone services, under the terms of the 1956 Consent Decree. Unix was thus available on a "no cost" (or very low cost) basis. The operating system was seen as an "in-house" tool on DEC and other computers and was in use throughout Bell Labs. Many universities used the same type of computer and were licensed by AT&T to utilize Unix. It thus spread widely. Schools picked it up, and computer science students used it to learn about operating systems, as Unix was a model of elegance and simplicity compared to most operating systems of the time. Unix became a widely used operating system in the academic world, paving the way for an inter national public communications system.

When Usenet was developed in 1979, it was created as a "Unix Users Network." The developers thought Usenet would provide a forum for people to solve problems they had in using Unix, as AT&T initially provided little external support for Unix. In an early handout, Usenet was referred to as a "poor man's ARPANET" [13]. In an e-mail message, Stephen Daniel explained that people who didn't have access to the ARPANET were hungry for similar opportunities to communicate [14].

Usenet has been full of surprises from the beginning. The originators of Usenet underestimated the hunger of people for meaningful communication. As Usenet was originally intended to provide an easy method of communicating with other users at the same site, the programmers thought people would want to have local bulletin boards [15]. However, people were attracted by the possibility of communicating with others outside the local community as well. Even today, the global communication it makes possible is part of what makes Usenet so enticing. It was also thought Netnews would be useful as a method of communication at individual locations, and between sites close to each other [16]. Usenet grew as a grassroots connection of people. The people who utilized Netnews wanted to communicate, and communicate they did! People have a fundamental need to communicate and Usenet aptly fills the bill [17].

By early 1981, the gap between the ARPANET and Usenet was bridged. The University of California at Berkeley had connections to both the ARPANET and Usenet. This allowed Usenet pioneer Mark Horton to bring mailing-list discussions from ARPANET mailing lists into Usenet news groups [ 18]. This was a significant achievement. Communities other than ARPA sponsored researchers were finally able to see what the ARPANET had made possible. The gatewaying of ARPANET mailing lists into Usenet attracted a wave of people when two ARPANET mailing lists (SF-Lovers and Human Nets) began to appear on Usenet. These lists provided interesting material and discussions. The size of the news feed (that is, the raw data of Usenet) thus became larger and provided more for people to read. Later, other sites would serve as gateways to even more discussion lists from the ARPANET. Netnews was also seen as a superior method of holding discussions. Gatewaying these FA (From ARPANET) newsgroups proved to be politically courageous. The ARPANET had been accessible to only a certain group of people, and these gateways challenged that notion. The effect on the ARPANET was important, as Steve Bellovin, another of the Usenet pioneers, wrote:

The impact of Usenet on the ARPANET was more as a (strong) catalyst to force reexamination (and benign neglect) on the strict policies against interconnection. UUCP mail into the ARPANET became a major force long before it was legit. And it was obviously known to, and ignored by, many of the Powers that Were [19].

Usenet, a network made possible by UUCP, expanded to connect people between two countries when the University of Toronto Zoology Department joined the Net in May 1981 [20]. Two companies, AT&T and DEC, proved helpful by distributing Netnews and electronic mail long distance. Each UUCP site had to either pay the phone bill to connect to the next system, or arrange for the other system to make the phone call. System administrators at AT&T and DEC did the legwork necessary to take e-mail and news where it might not have reached. However, easy connections were not always available. In one instance, Case Western Reserve University graduate students had to route mail across the continent twice in order to send mail through UUCP to reach their professors who were connected to the ARPANET next door [21]. Usenet encouraged connectivity to the ARPANET. Gradually, the ARPANET was interconnected with other networks, eventually functioning more as a backbone to other networks than as a self-contained network [22].

Contributed effort is the crucial foundation of WCPnet and Usenet. There are those who donate time and energy by contributing to Usenet's content - writing messages and answering messages or participating in debate. Without the time and effort put in by its users, Usenet would not be what it is today. Also important to Usenet's success are the system administrators who make the functioning of Usenet possible. Netnews takes up disk space on computers throughout Usenet, and in some cases phone calls must be made to transfer the raw data of the news. In particular, system administrators at AT&T and DEC found it worthwhile to transport Netnews across the country. Certain sites emerged as clearing houses for Usenet and WCP e-mail [23]. These computers served as major relay stations of both news and e-mail. A structure grew that became the "backbone" of"the Net." Backbone sites formed the trunk of the circulatory system of news and e-mail. A backbone site would connect to other central distribution computers and to numerous smaller sites. These central backbone sites provided a crucial organization to the Usenet communications skeleton, but people formed the center of these connections. For example, ihnp4 at AT&T existed mainly because of Gary Murakami's effort and only partially because of management support. Usenet services and support were not officially part of Murakami's job description. After Murakami left the Bell Labs Indian Hill Laboratoryin Naperville, Illinois, Doug Price put in the time and effort to keep things running smoothly. Certain system administrators in universities also picked up the responsibility for distributing Netnews and e-mail widely. Often these individuals would find ways of having their site pick up the phone bill. Sometimes sites would bill the recipients. Also, those who received a free connection were expected to provide the same to others [24].

At the beginning, expansion of the number of sites receiving Usenet was slow [25]. Why was this? Initially, Usenet was only transported via UUCP connections. Soon other resources were used, such as the airmailing of magnetic tape data to provide connectivity [ 26]. Today, Usenet travels over all types of connections. The evolving ARPANET (and now the Internet) provided a faster way of transporting Netnews. However, a large number of Usenet recipients still only have connectivity via UUCP. Universities and certain businesses can afford to connect to the Internet, but many individuals also want a connection. Even as late as 1992, when 60 percent of Usenet traffic was carried over the Internet via the instantaneous Network News Transport Protocol (NNTP), 40 percent of Usenet was still carried via the slower WCP connections. There are still many examples of various types of connections using UUCP. These representatives of the "fringe" provide a clue as to what the early days of this communication were like [27].

The number of sites receiving Usenet is continually increasing, demonstrating its popularity. People are attracted to Usenet because of what it makes possible. People want to communicate and enjoy the thrill of finding others across the country (or across the world) who share a common interest or with whom to be in contact. Besides the common thrill, it is possible to form serious relationships online. Usenet makes this discovery possible because it is a public forum. People expose their ideas broadly, making it possible to find compatriots in thought. The same physical connections which carry Usenet often also transport private electronic mail. However, the interactions and discoveries are only made possible by the public aspect of Usenet. Mailing lists have as wide a range of discussion, but are available to much smaller groups. Being on Usenet can become tiresome at times, [ 28] but it is rare that anyone leaves it permanently. Unless, of course, a person's life changes and this change means that time once spent online is no longer available. As more universities, schools, libraries, businesses, and individuals connect, the value of Usenet grows. Each new person can eventually add his or her unique opinion to the collection of thoughts and information that Usenet already has. Each new connection also increases the area where new connections can be made through cheap local phone calls. The potential for inexpensive expansion is limited only by the oceans, other natural barriers, or perhaps by mistaken government policies.

The ARPANET was supplemented by CSnet and eventually replaced by U.S. government funding of its successor, NSFnet. Both CSnet and NSFnet were created by the U.S. government in response to research scientists' and professors' pleas to have a network similar to the ARPANET. The NSFnet was also created to provide access to the five supercomputer computing centers around the country. The NSFnet, as the backbone of the U.S. portion of the Internet, provided another route for the distribution of Usenet. Similar to the ARPANET, NSFnet was a constant connection run over leased lines. One of the ways Netnews is distributed is using the NNTP protocol over connections. This allows for Netnews and e-mail to be distributed quickly over a large area. Internet connections also assist in carrying Usenet and e-mail internationally. The Internet-class networks and connections include the established government and university sponsored connections. However individuals at home are often connected by phone lines using SLIP, PPP, and various versions of WCP There are also commercial services that, for a fee, provide connections for electronic mail and Usenet access, as well as access to the Internet.

Much of the development of Usenet owes a big thanks to the early restrictions on commercial uses. Where else in our society has the commercial element been so clearly separated from any entity? Forums of discussion and communication become clogged and congested when advertisements use space. Because of the voluntary actions of those who use and redistribute Netnews and e-mail, many people on Usenet feel it wrong to assist commercial ventures. When people feel someone is abusing the nature of Usenet, they let the offender know through e-mail and in public messages. In this manner, users work to keep Usenet a forum free from commercial exploitation. Usenet has not been allowed to be abused as a profit-making venture for any one individual or group. Rather, people are fighting to keep it a resource that is helpful to society as a whole.

On what was the ARPANET and afterward the NSFnet portion of the Internet, there were Acceptable Use Policies (AUP) that existed because these networks were initially founded and financed by public money. On these networks, commercial usage was prohibited, which meant it was also discouraged on other networks that gatewayed into the NSFnet. Unfortunately, the NSF encouraged privatization of the NSFnet backbone [ 29]. However, the discouragement of commercial usage of the global Usenet is separate and developed differently from the AUP.

The social network that Usenet represents supersedes the physical connection it rides on. The current Netnews rides on many of the physical net works that exist today. However, if ever there were the need, Usenet could reestablish itself outside of the current physically organized networks. The essence of Usenet means it will survive because of its users' determination. Usenet draws its strength from being a peer-to-peer network. People who use Usenet do so because they wish to communicate with others. This communal wish means that people on Usenet find it in their own and in the community's interest to be helpful. In this way, Usenet exists as a worldwide community of resources ready to be shared. Where else today is there so much knowledge that is freely available? Usenet represents a living library and is an important part of the worldwide computer network.

The very nature of Usenet promotes change. Usenet was born outside of established "networks" and transcends any one physical network. It exists of itself and through other networks. It makes possible the distribution of information that might otherwise not be heard through "official channels." This role makes Usenet a herald for social change. Because of the inherent will to communicate, people who do not have access to Usenet will want access when they become exposed to it, and people who currently have access will want Usenet to expand its reach so as to further even more communication. Usenet could grow to provide a forum through which people influence their governments, allowing for the discussion and debate of issues in a mode that facilitates mass participation. This discussion becomes a source of independent information. An independent source is helpful in the search for the truth.

Administrators and individuals who handle the flow of information have been predicting the "imminent death of the Net" since 1982 [ 30]. The software that handles the distribution of Netnews has gone through several versions to handle the ever-increasing amount of information. People who receive Netnews have either had to decrease the number of days individual messages stay at the site or the number of newsgroups they receive; or they have had to allocate more disk space for the storage of Netnews. Despite all predictions and worries, the desire for communication has helped this social network develop and expand. Brad Templeton once wrote, "If there is a gigabit network with bandwidth to spare that is willing to carry Usenet, it has plenty more growth left" [31]. Various research labs have been working on producing usable gigabit networks.

Usenet is a democratic and technological breakthrough. The computer networks and Usenet are still developing. People need to work towards keeping connections available and inexpensive, if not free, so as to encourage the body of users to grow. There is a growing number of cities across the world where the public has access to computer networks as a civic service. This direction should be encouraged. Exclusive arrangements for access are to be discouraged. The very nature of Usenet means people are going to be working for its expansion. Others will be working for the expansion for their own gain, and some forces will be an active force against expansion of Usenet. I can only ask that people attempt to popularize and encourage the use of and fight for Usenet.
