Reference excerpt

The history of Internet in Sweden began with colleges and universities in the 1980s and then expanded through commercial operators to large companies and, in 1994, to the general public. In the 1970s, an innovation developed in Sweden by Torsten Cegrell was built into ARPANET, the precursor to the Internet. By the early 1980s, data links were established between some colleges and universities using modem access and UUCP. The first Internet connection in Sweden can be considered to have been in 1984, when a Swedish network was connected to the ARPANET using TCP/IP. In 1988 direct access to the Internet was created in the form of the SUNET and NORDUnet university and college networks, which in turn was connected to the USA. In 1991, Swipnet started operations and became Sweden's first ISP. In 1994, providers started offering Internet access to private individuals. In 1994, Swedish Prime Minister Carl Bildt and Bill Clinton became the first heads of government in the world to email each other. In 1997, the Swedish government decided that anyone who bought a personal computer at home could deduct the cost. The aim of the reform was to increase digital literacy in Sweden. This decision, known as the Home PC Reform, contributed to an increase in the use of computers and the internet by Swedes. In 2003, some telephony also moved online, through Niklas Zennström's Skype service. Skype was then bought by the auction site eBay for billions. The service made international calls free, among other things. File sharing and online privacy became an increasingly important issue, especially for young adults who grew up with the Internet. In 2006, the Pirate Party was founded, and in 2009 it was voted into the European Parliament. Also in 2006, paradoxically, a service was founded that would kill file sharing of music in Sweden: the streaming music service Spotify.

1960s, 1970s and 1980s

The Internet's predecessor, the ARPANET, carried its first packets in 1969 in the United States using data communication techniques invented and first-implemented by Donald Davies for the NPL network in the United Kingdom. The network research community formed the International Network Working Group (INWG) in 1972, of which Kjell Samuelson, a doctoral student at Stockholm University, was a member. The ARPANET grew rapidly and, in June 1973, the first connection outside the United States was a transatlantic satellite link to the Norwegian Seismic Array (NORSAR), via the Tanum Teleport Earth Station in Sweden. The following month, this connection was extended to Peter Kirstein's research group at University College London, which evolved into SATNET. In the 1960s, ASEA was commissioned by Vattenfall to create a computer-based monitoring system to reduce the risk of disturbances in Sweden's power grid. This grid was connected with those of Finland, Norway and Denmark. Up until then, the telephone was the main tool for engineers monitoring the power grid. For this purpose an ARPANET-like network, TIDAS, was developed by ASEA between 1972 and 1975. The TIDAS network included split horizon route advertisement, an innovation to prevent routing loops developed by Swedish researcher Torsten Cegrell, which was soon built into the ARPANET and thus the Internet. The KOM system became central to the history of the Internet in Sweden. In 1978, it was developed at the Stockholm Computer Center, by Jacob Palme and Torgny Tholerus. The KOM system was a Bulletin board system (BBS) where users could connect to a central computer and discuss with each other, play games and exchange files. From 1982, users of the KOM system could also send e-mails via a connection to ARPANET. In 1979, Televerket started its Datavision service (later called Videotex), to which people connected with modems and special software and subscriptions. It was offered commercially in 1982. Many large companies adopted the service, but otherwise it was not widely used. The service was discontinued in 1993. The first Swedish non-profit BBS was started in 1980 by the ABC-Club. An association for users of the ABC 80 home computer. Patrik Fältström was a mathematics student in Stockholm in the early 1980s when he was hired to help build and test the infrastructure for the ARPANET.

TCP/IP or X.25

In the 1980s, there was disagreement about whether TCP/IP or X.25 should be used as the technology for communicating information over packet-switching networks. Telecommunications companies in Europe and North America preferred X.25 virtual circuits, which had built-in error control and made it easier for operators to track connection usage, and they built public data networks based on this protocol. In Sweden, Televerket's system for this was called Datapak. In the end, adoption of TCP/IP overwhelmed other protocols. Some consider that the Internet was born on January 1, 1983, when ARPANET switched from two-way communication with NCP to TCP/IP, although SATNET, including Norway and University College London, adopted TCP/IP the previous year. The X.25 protocol is still used in private networks that need extra security, such as credit card terminals and ATMs.

E-mail

A UUCP link was established via EUnet in 1982 connecting Sweden, the Netherlands, Denmark and the United Kingdom. The first e-mail message received in Sweden was sent by Jim McKie from the Amsterdam Mathematics Centre to Björn Eriksen at ENEA AB in Stockholm on April 7, 1983. To receive the message, Eriksen had connected a VAX 780 computer to the European part of the Internet with a 1200 bit/s modem. The computer terminal that received the message, a Digital DECwriter III, has been located at the National Museum of Science and Technology in Stockholm since October 2023. In the early summer of 1984, Sweden got its first own part of the Internet, when research assistant Ulf Bilting at Chalmers University of Technology in Gothenburg connected the local network at the Department of Computer Science as IP network number 192.5.50.0, which is then connected to ARPANET.

Illustrations

Worked examples

Example 1 — a first encounter with History of the Internet in Sweden

Start with the simplest possible case. Write down what History of the Internet in Sweden claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to History of the Internet in Sweden before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about History of the Internet in Sweden ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of History of the Internet in Sweden

In research: History of the Internet in Sweden appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses History of the Internet in Sweden in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: History of the Internet in Sweden is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of the Internet, Internet in Sweden, so understanding it makes those chapters shorter.
In everyday life: Look for History of the Internet in Sweden outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
