History
One theory of its origin is that it was a Latin exclamation of joy (io), written with the I above the o.
The exclamation mark was first introduced into English printing in the 15th century, and was called the "sign of admiration or exclamation" or the "note of admiration" until the mid-17th century; admiration referred to its Latin sense of wonderment.
The exclamation mark did not have its own dedicated key on standard manual typewriters before the 1970s. Instead, one typed a period, backspaced, and typed an apostrophe. In the 1950s, secretarial dictation and typesetting manuals in America referred to the mark as "bang", perhaps from comic books where the ! appeared in dialogue balloons to represent a gun being fired, although the nickname probably emerged from letterpress printing. This bang usage is behind the titles of the interrobang, an uncommon typographic character, and a shebang line, a feature of Unix computer systems.
