How Modern Telecommunications Evolved from the Telegraph to the Internet

Andrew Wheen

DOT-DASH TO DOT.COM: How Modern Telecommunications Evolved from the Telegraph to the Internet The profusion of websites and applications that characterize the modern Internet may seem a far cry from the primitive telegraph systems 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.

How did this happen? What were the inventions that shaped modern communications? Who were the key players in this amazing story? How does the Internet work? And what is coming next? This fascinating and long-overdue book answers these and many other questions, bringing to life the characters, the times they lived in, and the technological revolution that they brought about.
