In the 1800s cities used pneumatic tubes to transfer physical documents. Of course with the internet we no longer need these long tunnels, but that doesn't mean that they aren't fun to learn about how these old systems are similar to the internet. Molly Wright Steenson gave a great talk about how these systems worked and what was state of the art in the 1800's.
