In the World of Commerce
In the business world, the at sign often precedes a company’s domain in email addresses. It has become synonymous with professionalism and is used in official communications worldwide.
In business, @ is a symbol that means “at” or “each.” For example, it means “each” in “4 apples @ $.35 = $1.40.” Perhaps because it was one of the standard characters designed on typewriters (usually with the upper shift key pressed), @ was chosen to be included as one of the special characters in the ASCII character set that became standard for computer keyboards, programs, and online messaging. In July 1972, while the File Transfer Protocol (FTP) specifications were being written, someone suggested including some email programs written by Ray Tomlinson, an engineer at Bolt Beranek and Newman, prime contractor for ARPANet. Projects Agency Network), the forerunner of the Internet.
Tomlinson…became best known for a brilliant (he called it obvious) decision he made while writing shows. He needed a way to separate, in the email address, the user's name from the machine the user was on. How should that be indicated? He wanted a character that would not, under any circumstances, be found in the username. He looked at the keyboard he used, a model 33 teletype, also used by almost everyone on the net. In addition to letters and numbers, there were a dozen punctuation marks. "I got there first, so I was able to choose whatever punctuation marks I wanted," Tomlinson said. "I chose the @ sign." The character also had the advantage of meaning "in" the designated institution. He had no idea that he was creating an icon for the connected world.
