@


The at-sign, @, normally read aloud as "at", also commonly called the at symbol or commercial at, and less commonly a wide range of other terms, is originally an accounting and commercial invoice abbreviation meaning "at the rate of" (e.g. 7 widgets @ £2 = £14). It was not included on the keyboard of the earliest commercially successful typewriters, but was on at least one 1889 model[5] and the very successful Underwood models from the "Underwood No. 5" in 1900 onward. It is now universally included on computer keyboards. The mark is encoded at U+0040 @ commercial at (HTML:@).
