If you see articles claiming that V.A. Shiva Ayyadurai invented email, ignore them. He did no such thing, unless he invented when it he was two years old in 1965.
โProbably the first email system of this type was MAILBOX, used at Massachusetts Institute of Technology from 1965. Another early program to send messages on the same computer was called SNDMSG.โ
And the first email sent over ARPANET occurred in 1971, seven years before he claims to have โinventedโ email.
Hell, my grandfather was sending and receiving email at Purdue in the early- to mid-1970s.
In truth, no one person invented email. It was developed over time from very basic beginnings, building on older things as all tech does, and evolved with said technology.
Nearly all email conventions, practices and technologies, however, had already been developed by 1978. Ayyadurai had nothing to do with it.
