TEXTING: Before there was texting there were telegrams

I love texting. It's a concise and efficient means of communication. No, of course it doesn't replace conversation and actual face-to-face time spent together, but for "Running 5 mins late" or "Can you pick up pizza" or "Radio 2 is playing 1979 greatest hits," nothing compares.
Of course, there is nothing new under the sun. Emily Post's etiquette book, circa 1937, noted that, for identical reasons, telegrams were quickly replacing written or phoned invitations:
"Telephoning a message and fifty names to the telegraph office takes at most five minutes, whereas calling each of the fifty numbers (including busy signals and messages left for those not at home, and enforced conversation with those who talk for half an hour) would take anywhere from twice to ten times as long."
