The timeline stopped short of marine distress radio innovations.

2012- Costa Concordia's Captain uses lifeboat radio communications, setting new protocols on ensuring the ships Captain and crew remain safe. Experts say this new use of lifeboat communications will have the effect of saving the lives of countless ships Captains involved in maritime disasters. (There was no comment on the safety of the passengers.)

500khz and 2182khz used to be emergency frequencies.Now I hear it's all satellite.

Another change that was brought about by the Titanic was the requirement that ships must have enough lifeboats on EACH side of the vessel to accommodate everyone on board. When a ship is listimg hard enough to one side, the lifeboats on the other side could not be lowered. The Titanic was the first time the international distress signal “SOS” was ever used. FWIW.

Marconi was a thief.

I have often heard that one problem that was highlighted by the Titanic sinking was that radio transmission in those days did not really involve defined frequencies, so there was a lot of interference and confusion among different transmitters.

I was thinking that an IEEE Spectrum article might get into the details of this, but this one doesn't.
