We have laid out our own electric networks on a global scale by cable, by telegraph, by radio, by all sorts of electric means.
These circuits are loaded with data that move instantly and which have become indispensable to all decision makers in business, in education, and in politics.
These circuits have a peculiar character not just of connecting us with one another but of involving us with one another.
It is because of the speed. With circuitry the feedback occurs at the same moment the event occurs. - Marshall McLuhan
