The Telegraph

The profusion of websites and applications that characterise the modern Internet may seem a far cry from the primitive telegraph system of the late 1830s. There is, however, a direct link. The invention of the electric telegraph paved the way for telephone networks which, in turn, laid the foundations for today's Internet. In less than 170 years, simple arrangements of magnets, switches and cables evolved to become the largest and most complex machine in the world.
