In the first decade of the 20th century, the Continuous Quality Development (CQD) distress signal system was replaced by the SOS signal. The SOS signal was introduced at the International Radiotelegraphic Convention in 1906 and became widely adopted due to its simplicity and effectiveness in Morse Code. Its distinctive pattern made it easier to recognize, leading to improved communication during emergencies at sea.
