Opening the network to commerce

The interest in commercial use of the Internet became a hotly debated topic. Although commercial use was forbidden, the exact definition of commercial use could be unclear and subjective. UUCPNet and the X.25 IPSS had no such restrictions, which would eventually see the official barring of UUCPNet use of ARPANET and NSFNet connections. Some UUCP links still remained connecting to these networks however, as administrators cast a blind eye to their operation.

During the late 1980s, the first Internet service provider (ISP) companies were formed. Companies like PSINet, UUNET, Netcom, and Portal Software were formed to provide service to the regional research networks and provide alternate network access, UUCP-based email and Usenet News to the public. The first commercial dialup ISP in the United States was The World, opened in 1989.

In 1992, Congress allowed commercial activity on NSFNet with the Scientific and Advanced-Technology Act, 42 U.S.C. § 1862(g), permitting NSFNet to interconnect with commercial networks. This caused controversy amongst university users, who were outraged at the idea of noneducational use of their networks.^{[citation needed]} Eventually, it was the commercial Internet service providers who brought prices low enough that junior colleges and other schools could afford to participate in the new arenas of education and research.^{[citation needed]}

By 1990, ARPANET had been overtaken and replaced by newer networking technologies and the project came to a close. In 1994, the NSFNet, now renamed ANSNET (Advanced Networks and Services) and allowing non-profit corporations access, lost its standing as the backbone of the Internet. Both government institutions and competing commercial providers created their own backbones and interconnections. Regional network access points (NAPs) became the primary interconnections between the many networks. The final commercial restrictions ended in May 1995 when the National Science Foundation ended its sponsorship of the Internet backbone.

Internet Engineering Task Force

Requests for Comments (RFCs) started as memoranda addressing the various protocols that facilitate the functioning of the Internet and were previously edited by the late Dr. Postel as part of his IANA functions.

The IETF started in January 1985 as a quarterly meeting of U.S. government funded researchers. Representatives from non-government vendors were invited starting with the fourth IETF meeting in October of that year.^{[citation needed]} In 1992, the Internet Society, a professional membership society, was formed and the IETF was transferred to operation under it as an independent international standards body.^{[citation needed]}

NIC, InterNIC, IANA and ICANN

The first central authority to coordinate the operation of the network was the Network Information Centre (NIC) at Stanford Research Institute (SRI) in Menlo Park, California. In 1972, management of these issues was given to the newly created Internet Assigned Numbers Authority (IANA). In addition to his role as the RFC Editor, Jon Postel worked as the manager of IANA until his death in 1998.

As the early ARPANET grew, hosts were referred to by names, and a HOSTS.TXT file would be distributed from SRI International to each host on the network. As the network grew, this became cumbersome. A technical solution came in the form of the Domain Name System, created by Paul Mockapetris. The Defense Data Network—Network Information Center (DDN-NIC) at SRI handled all registration services, including the top-level domains (TLDs) of .mil, .gov, .edu, .org, .net, .com and .us, root nameserver administration and Internet number assignments under a United States Department of Defense contract. In 1991, the Defense Information Systems Agency (DISA) awarded the administration and maintenance of DDN-NIC (managed by SRI up until this point) to Government Systems, Inc., who subcontracted it to the small private-sector Network Solutions, Inc.

Since at this point in history most of the growth on the Internet was coming from non-military sources, it was decided that the Department of Defense would no longer fund registration services outside of the .mil TLD. In 1993 the U.S. National Science Foundation, after a competitive bidding process in 1992, created the InterNIC to manage the allocations of addresses and management of the address databases, and awarded the contract to three organizations. Registration Services would be provided by Network Solutions; Directory and Database Services would be provided by AT&T; and Information Services would be provided by General Atomics.

In 1998 both IANA and InterNIC were reorganized under the control of ICANN, a California non-profit corporation contracted by the United States Department of Commerce to manage a number of Internet-related tasks. The role of operating the DNS system was privatized and opened up to competition, while the central management of name allocations would be awarded on a contract tender basis.

Globalization and 21st century

Main article: Internet governance

Since the 1990s, the Internet's governance and organization has been of global importance to commerce. The organizations which hold control of certain technical aspects of the Internet are both the successors of the old ARPANET oversight and the current decision-makers in the day-to-day technical aspects of the network. While formally recognized as the administrators of the network, their roles and their decisions are subject to international scrutiny and objections which limit them. These objections have led to the ICANN removing themselves from relationships with first the University of Southern California in 2000, and finally in September 2009, gaining autonomy from the US government by the ending of its longstanding agreements, although some contractual obligations with the Department of Commerce continue until at least 2011. The history of the Internet will now be played out in many ways as a consequence of the ICANN organization.

In the role of forming standard associated with the Internet, the IETF continues to serve as the ad-hoc standards group. They continue to issue Request for Comments numbered sequentially from RFC 1 under the ARPANET project, for example, and the IETF precursor was the GADS Task Force which was a group of US government-funded researchers in the 1980s. Many of the group's recent developments have been of global necessity, such as the i18n working groups who develop things like internationalized domain names. The Internet Society has helped to fund the IETF, providing limited oversight.

Use and culture

E-mail and Usenet

Main articles: e-mail, Simple Mail Transfer Protocol, and Usenet

E-mail is often called the killer application of the Internet. However, it actually predates the Internet and was a crucial tool in creating it. E-mail started in 1965 as a way for multiple users of a time-sharing mainframe computer to communicate. Although the history is unclear, among the first systems to have such a facility were SDC's Q32 and MIT's CTSS.

The ARPANET computer network made a large contribution to the evolution of e-mail. There is one report indicating experimental inter-system e-mail transfers on it shortly after ARPANET's creation. In 1971 Ray Tomlinson created what was to become the standard Internet e-mail address format, using the @ sign to separate user names from host names.

A number of protocols were developed to deliver e-mail among groups of time-sharing computers over alternative transmission systems, such as UUCP and IBM's VNET e-mail system. E-mail could be passed this way between a number of networks, including ARPANET, BITNET and NSFNet, as well as to hosts connected directly to other sites via UUCP. See the history of SMTP protocol.

In addition, UUCP allowed the publication of text files that could be read by many others. The News software developed by Steve Daniel and Tom Truscott in 1979 was used to distribute news and bulletin board-like messages. This quickly grew into discussion groups, known as newsgroups, on a wide range of topics. On ARPANET and NSFNet similar discussion groups would form via mailing lists, discussing both technical issues and more culturally focused topics (such as science fiction, discussed on the sflovers mailing list). >>next>>
