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.

Aeneas Tacitus, a Greek military scientist and cryptographer, invented an optical communication system that combines water and beacon telegraphy. Torches indicated the beginnings and the ends of message transmissions while water jars were used to transmit the messages. These jars had a plugged standard-size hole drilled on the bottom side and were filled with water. As those who sent and those who received the message unplugged the jars simultaneously, the water drained out. Because the transmitted messages corresponded to water levels, the sender indicated by torch signal that the appropriate water level has been reached. It is a disadvantage that the possible messages are restricted to a given code, but as this system was mainly used for military purposes, this was offset by the advantage that it was almost impossible for outsiders to understand these messages unless they possessed the codebook.
With communication separated from transportation, the distant became near.
Tacitus' telegraph system was very fast and not excelled until
