Remember the telegram?
For those of us over the age of 30, the telegram was email's great-granddaddy.
A message at Point A gets encoded into Morse Code, then sent out through the wires to a station at Point B.
It then gets decoded back into plain language and sent out to the proper addressee at Point C via courier.
Waaaaayyy baaaack in the daaaaaaayyyy, it was cheaper than making a long-distance call.
How times have changed. What's next?
