Where does come from?
In the early 1900s, SOS was adopted as the international distress signal, chosen because the letters S, O, and S are clear and easy to transmit in Morse code (- – – –– – – -).
While it was originally sent out by ships imperiled at sea, SOS spread as a shorthand for “emergency” more generally in the 20th century.
It was approved as an emoji in 2010 under Unicode 6.0, officially called Squared SOS but popularly going by SOS button, emergency, or simply SOS emoji.
The emoji is fairly uniform across platforms, depicting a rounded red square with SOS in white letters.
Who uses ?
The squared SOS emoji sometimes marks content noting actual emergencies or emergency services, such as when responders are on the scene or when alerts have been issued.

Take a break and hydrate! Caffeine and stress are both heavy contributors to dehydration. Put down the textbook for a minute to refresh with SOS so you can get back studying without the fatigue and decreased focus caused by dehydration!! 📸: @andrew.kitto #sosrehydrate #soscollege #drinkableiv #🆘 #hydratesmarter #deadweek #finals #study #exams #collegelife
