The advantage of the transatlantic cable was that it took less time to transmit messages. In 1866 a voyage across the Atlantic could take months, so sending letters and getting answers could take over months. the transatlantic cable could transmit 1 word every 10 min which was a great improvement in communication devices the first message sent with the transatlantic cable was from Queen Victoria to president James Buchanan and it took 16h30min to transmit a 99 word message.
I wanted to visit Europe, so I took a transatlantic flight to London. The first transatlantic flight took place in the early 20th century. The Titanic was unable to complete her first transatlantic crossing. My international communications still rely on the transatlantic cable.
