Great question – but I have no idea! It must come from an early protocol, thinking of how to group together people within a network who lived ‘at’ a particular address..
In the early days of the internet, a standard, computer-readable format for all e-mail addresses was defined. According to that standard, it would consist of a user name and a domain name (comparable to an address on an envelope having a name of a person and a description of a location, with a street, zip code etc.). The two were to be put together in the form “user at domain”. The symbol @ was at that time already used in accounting and pronounced “at” (as in “three apples at one pound each”), and it had the additional advantage of not being likely to be used in user names or domain names.
I used to know, but now all I know is that it organizes messages by what domain the messages should be sent to. It’s like sending a letter to a certain post code.
The @ sign was chosen by Ray Tomlinson because name ‘at’ organisation sounds right, but more over because it is Shift-2 was right there on the keyboard,easy to type and didn’t have much use elsewhere in written language at the time.
Thanks for that comment! I had a little problem with I’m A Scientist chats today, since I had to Shift-2 on my American laptop (to get @) for one chat session and then Shift-quote for another session, since I have a British keyboard at the uni where I work.
