I was specifically referring to the ability to communicate in writing at that speed. I guess the telegraph technically existed as well, but it was expensive and awkward.
And couldn’t reach across oceans, required special training, and only accommodated short messages because of the tedious nature of signaling.
You could definitely send telegraphs overseas, and sending or receiving them required no training.
and sending or receiving them required no training.
If you mean paying someone to send them, then sure. But it required learning Morse code, and learning to use a keyer.
You couldn’t send them overseas until after the invention of radio. Before that the signal traveled along a wire they laid the transatlantic cable.
