(· · · – – – · · ·).

From the
beginning, the SOS distress signal has really consisted of a continuous
sequence of three-dits/three-dahs/three-dits, all run together without letter
spacing. In International Morse Code, three dits form the letter S, and three
dahs make the letter O, so "SOS" became an easy way to remember the
order of the dits and dahs. In modern terminology, SOS is a Morse
"procedural signal" or "prosign", and the formal way to
write it is with a bar above the letters: SOS.
In popular
usage, SOS became associated with such phrases as "save our ship",
"save our souls" and "send out succour". These may be
regarded as mnemonics, but SOS does not actually stand for anything and is not
an abbreviation, acronym or initialism. In fact SOS is only one of several ways
that the combination could have been written; VTB, for example, would produce
exactly the same sound, but SOS was chosen to describe this combination. SOS is
the only 9-element signal in Morse code, making it more easily recognisable, as
no other symbol uses more than 8 elements.
This distress signal was first adopted by the German government in radio regulations effective April 1, 1905, and became the worldwide standard under the second International Radiotelegraphic Convention, which was signed on November 3, 1906 and became effective on July 1, 1908. SOS remained the maritime radio distress signal until 1999, when it was replaced by the Global Maritime Distress Safety System. SOS is still recognized as a visual distress signal.

The first
recorded use of the “SOS” as a distress signal was just over a year later, in
August, 1909. The wireless operators on the SS Arapahoe sent the signal when
the ship was disabled by a broken propeller off the coast of Cape Hatteras,
North Carolina.
