The success of the invention …

The companies who provided underwater telegraph cables across the Atlantic obstructed Marconi's invention, since it threatened their monopoly on communications.  But the great advantages and notable technical developments of radio transmissions meant that their use expanded rapidly.

The company founded by Marconi in 1900 Marconi's Wireless Telegraph Co. Ltd – worked on extending services between Europe and America and on installing radio apparatus on ships.

And now a brief reminder of some of the never-ending experimental and applicative endeavours of Marconi and his technicians.
In 1899 the Royal Navy equipped three warships with the new radio apparatus, and private ships soon followed.
In 1902, from onboard the Italian Navy's battleship Carlo Alberto, Marconi made radio transmissions across the mountain chains of Europe.
In 1903 he transmitted a news bulletin by radiotelegraphy between ground stations and some transatlantic liners.
In 1909 he carried out his first experiment in voice broadcasting via radio waves, which was to develop into radio broadcasting after World War I.

Fig. 2: Marconi's Wireless announcement in the Daily Mirror of 30 July 1910 describes the arrest of two wanted men as the ship Monrose, on which they had escaped, arrived in Canada - thanks to the message sent by the ship's radio.

Again in 1909, thanks to an SOS message sent from the ship's radio, Marconi's invention permitted the first sea rescue of the survivors of the Florida and Republic which had collided in the Atlantic.  But it was on 14 April 1912 that the radio received tremendous public acclaim worldwide, when some of the passengers of the Titanic were rescued thanks to Marconi radio operators who continued transmitting while the liner went down.
