Background

SOS was introduced in 1905 by the German government during the rise of maritime radio communication. In 1908, it became globally recognized under the International Radiotelegraph Convention.
Why “SOS” Was Chosen

As communication shifted from Morse to radio, then to texting and digital messaging, SOS transformed:
