telegraph networks
Wired message systems
Telegraph networks were systems of interconnected telegraph stations that transmitted electrical signals over wires across distances.
Developed in the mid-nineteenth century, they enabled near-instantaneous long-distance communication for the first time, revolutionizing commerce, journalism, and military operations.
Messages traveled station to station, often requiring relay operators to retransmit signals.
The telegraph network spread news of Lincoln's assassination within hours.
The term now appears mainly in historical contexts, though it serves as a conceptual ancestor to modern telecommunications infrastructure.
