The concept of real time communication begin in '1800The culture of instant information sharing was born in the 1800s. Back then, news and stock trade transactions would have already traveled in real time over 650,000 km of telegraph network.In the last century you could chat online by means of HAM radio, a network entirely built by devoted hobbyists. Access to HAM radio wasn't available to everybody; good technical skills and motivation were required.Being connected at all times is now considered a right. However, the systems may eventually fail and leave us isolated. Only the HAM radio network can provide emergency communication links. When we re-discover these technologies, we should ask ourselves: how our present world will be viewed in the future? The exhibit, usually held in the context of Cagliari Festival Scienza, is aimed at showing how real-time communication has existed for almost 200 years and its probable developments.
