This book discusses the interesting parallels between the development of the telegraph in the late 1800s and the internet in the late 1990s. The comparison doesn't feel forced and reveals lots of interesting common tidbits. For instance, as on the internet, encryption was a feature of telegraphy. Crucial information, such as the box office returns of the latest Gilbert and Sullivan production, were encrypted using commercially available codebooks before getting tapped out across the public network. There were even affairs and marriages over the telegraph, just as with the internet a century later.
