The first transatlantic telegraph cable was laid down in 1854 and radio waves weren’t even theorized until 1873… https://en.wikipedia.org/wiki/Transatlantic_telegraph_cable

I kinda suspected I might be wrong about that as I was typing it, and then I was like “Nah! That’s just silly. Of course they didn’t run a cable across the entire Atlantic Ocean in the 1800’s!”. But I was wrong. That’s actually really impressive.
