You’ve got mail

InternetsComputer engineer and recent MIT graduate Ray Tomlinson, working on the nascent ARPANET project, adds minor new features to an experimental file transfer protocol and, in so doing, sends the first network e-mail. This first message doesn’t have far to travel – it arrives at another computer terminal in the same room – but it is the beginning of e-mail on ARPANET, a feature which is adopted so widely and so quickly that it accounts for 75% of all ARPANET data traffic just two years later. Tomlinson is also credited for inventing the user@destination e-mail address format.
