A Brief History

"SOS" was established as an international distress signal in 1906 by the International Wireless Telegraph Convention. Contrary to popular belief, "SOS" does not stand for any phrase, such as "Save Our Souls" or "Save Our Ship." Instead, it was chosen because the Morse code representation for "SOS" (· · · — — — · · ·) is unmistakable and easily recognizable, even in the most challenging conditions.

Why SOS?

The simplicity and effectiveness of the Morse code sequence for "SOS" make it universally understood. The signal is quick to transmit and can be easily identified amidst noise and poor signal conditions, which are common during emergencies.

SOS in Modern Times

While Morse code is less commonly used today, the term "SOS" has transcended its original medium. It's now a general term for any request for help or emergency signal, regardless of the communication method.

Examples of SOS Usage

Understanding and recognizing an "SOS" signal can be crucial in saving lives. It's a universal call for help that transcends language barriers, making it an essential part of safety protocols in various scenarios.

How to Respond to an SOS
