The Boy Who Invented Email

In 1978, a 14-year-old boy invented email.

He created a computer program, which he called “email,” that replicated all the functions of the interoffice mail system: Inbox, Outbox, Folders, Memo, Attachments, Address Book, etc., the now familiar parts of every email system.

On August 30, 1982, the US government officially recognized V.A. Shiva Ayyadurai as the inventor of email by awarding him the first US Copyright for “Email,” “Computer Program for Electronic Mail System,” for his 1978 invention. This was awarded at a time when Copyright was the only way to protect software inventions.”

Read the fascinating account of the invention of email in this article (first in a series about its history) from the huffingtonpost.

That’s funny, because RFC 733 was published 21 November, 1977. And states:

Essentially, we specify a revision to  ARPANET  Request  for
Comments (RFC) 561, "Standardizing Network Mail Headers", and RFC
680, "Message Transmission Protocol".  This revision removes  and
compacts  portions  of  the  previous  syntax  and  adds  several
features to network address  specification.   In  particular,  we
focus  on  people  and  not  mailboxes  as  recipients  and allow
reference to stored address lists.   We  expect  this  syntax  to
provide  sufficient  capabilities  to  meet most users' immediate
needs and, therefore, give developers enough  breathing  room  to
produce  a new mail transmission protocol "properly".

It’s successor, RFC 822, published in 1982 was the standard for email for almost 20 years. 

The kid just copyrighted a program named ‘email’.
