Cablegram
From Wikipedia, the free encyclopedia
Not to be confused with Kabalgram.
A cablegram, sometimes shortened to just cable, was a telegram, a text possibly encrypted, which was transmitted through the means of an electrical cable, underwater (the submarine communications cables) or aerial.
Initially only available to governments, it was later made accessible to private companies. Submarine cables were a point of conflict between nations between 1850 and 1939, and have been addressed by several diplomatic conventions.[citation needed] At the beginning of 20th century, the development of radio transmission technologies, brought to the replacement of cablegrams with radiograms.
