Talking with some friends you have never physically met

I met a discussion about how long ago people started talking electronically two people that they had never physically met. I was surprised to remember that it was sending code through ham radio. Somewhere back in the 1950s.

It then went 2 voice discussion over CB radio, and back to typing when multics had the first email, which originally was not even between multiple computers. Since then it has moved until currently there are probably a dozen of ways to talk to people in the Millions, and probably at least 100 in small connections.

The oldest was Morse Telegram. That moves back into the end of the 1800s. January 11th 1838 to be exact.
