therewithal 's review for:
The Victorian Internet
by Tom Standage
I did wish the book had spent more time on the "online" culture that developed among the telegraph operators and less on who invented what when, but it was pretty fascinating anyway. And I didn't know the optical telegraph had been a thing. (I had thought the clacks in Discworld were just an extended joke substituting semaphore for Morse code but no, they essentially really existed.)
