Association for Progressive Communication (APC)

The APC is a global federation of 24 non-profit Internet providers serving over 50,000 NGOs in 133 countries. Since 1990, APC has been supporting people and organizations worldwide, working together online for social, environmental and economic justice. The APC's network of members and partners spans the globe, with significant presence in Central and Eastern Europe, Africa, Asia and Latin America.

History

Between 1982 and 1987 several independent, national, non-profit computer networks emerged as viable information and communication resources for activists and NGOs. The networks were founded to make new communication techniques available to movements working for social change.

In 1987, people at GreenNet in England began collaborating with their counterparts at the Institute for Global Communications (IGC) in the United States. These two networks started sharing electronic conference material and demonstrated that transnational electronic communications could serve international as well as domestic communities working for peace, human rights and the environment.

This innovation proved so successful that by late 1989, networks in Sweden, Canada, Brazil, Nicaragua and Australia were exchanging information with each other and with IGC and GreenNet. In the spring of 1990, these seven organizations founded the Association for Progressive communications to co-ordinate the operation and development of this emerging global network of networks.

Strategies and Policies

The APC defends and promotes non-commercial, productive online space for NGOs and collaborates with like-minded organizations to ensure that the information and communication needs of civil society are considered in telecommunications, donor and investment policy. The APC is committed to freedom of expression and exchange of information on the Internet.

The APC helps to build capacity between existing and emerging communication service providers.

The APC Women's Networking Support Program promotes gender-aware Internet design, implementation and use.

Through its African members, the APC is trying to strengthen indigenous information sharing and independent networking capacity on the continent.

Members of APC develop Internet products, resources and tools to meet the advocacy, collaboration and information publishing and management needs of civil society. Recent APC initiatives have included the APC Toolkit Project: Online Publishing and Collaboration for Activists and the Mission-Driven Business Planning Toolkit.

The APC also runs special projects like the Beijing+5, which shall enable non-governmental organizations to actively participate in the review of the Beijing Platform for Action.

Optical communication system by Aeneas Tacitus, 4th century B.C.

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 the end of the 18th century.
