At the beginning of the story of today's global data networks is the story of the development of In 1955 President Eisenhower announced the USA's intention to launch a satellite. But it in the end it was the Soviet Union, which launched the first satellite in 1957: Sputnik I. After Sputnik's launch it became evident that the Cold War was also a race for leadership in the application of state-of-the-art technology to defense. As the US Department of Defense encouraged the formation of high-tech companies, it laid the ground to Silicon Valley, the hot spot of the world's computer industry. The same year as the USA launched their first satellite - Explorer I - data was transmitted over regular phone circuits for the first time, thus laying the ground for today's global data networks. Today's satellites may record weather data, scan the planet with powerful cameras, offer global positioning and monitoring services, and relay high-speed data transmissions. Yet up to now, most satellites are designed for military purposes such as reconnaissance. 1969 ARPAnet was the small network of individual computers connected by leased lines that marked the beginning of today's global data networks. An experimental network it mainly served the purpose of testing the feasibility of In 1969 ARPANET went online and linked the first two computers, one located at the University of California, Los Angeles, the other at the Stanford Research Institute. Yet ARPAnet did not become widely accepted before it was demonstrated in action to a public of computer experts at the First International Conference on Computers and Communication in Washington, D. C. in 1972. Before it was decommissioned in 1990, In the USA it was already in 1994 that commercial users outnumbered military and academic users. Despite the rapid growth of the Net, most computers linked to it are still located in the United States. 1971 Invention of 1979 Introduction of 1992 Launch of the |

B2-92 B2-92 is an independent FM radio station based in Belgrade, which has won a number of international press and media awards. Their broadcasts and music and uncensored news heard across Serbia through a network of local partner stations. Their signal was also picked up by the BBC World Service and retransmitted via satellite around the world. In December 1996, B2-92 began using technology to stream live audio broadcasts and short video clips over the Internet. Strategies and Policies From its start as a terrestrial broadcaster B2-92 has been a respected source of independent news in the Balkans. Although B2-92 has been constantly subjected to repression and threat by government authorities it continued to provide music and news. When in December 1996 B2-92 was banned from broadcasting it began to distribute its content via streaming audio and video on its website. A web savvy support group was formed helping B2-92 to continue its distribution of news. Anonymous e-mail lists were developed to protect the identity of those wishing to express their views about the war, as well as a message boards linking to the Help B2-92 Campaign site. Furthermore encrypted e-mail services were provided for journalists and others in the former Yugoslavia who found themselves under threat. B2-92 also co-operates with various media activists and support groups and networks, which help B2-92 to continue its content distribution. |
