| Today is 100th anniversary of 'SOS'
Tuesday marked the 100th anniversary of the introduction of the Morse code "SOS" signal as the universal call of help on the high seas.
The Times of London said SOS replaced CQD as the most commonly used distress signal in 1908 because its three dots, three dashes, three dots makeup was less likely to be misinterpreted on the receiving end.
A year later, the Times said, everyone aboard the liner Slovinia was rescued after the stricken ship was able to send an SOS off the Azores.
Complete adoption of SOS didn't come about until the Titanic went down and some ships in the area ignored its SOS and CQD signals.
