1) Introduced electrical impulses over wires to rapidly send coded language messages over long distances in a near-instant.
2) Improved communication speed across larger territories, including intercontinental communication with undersea telegraph cables by the 1860s.
The Telephone:
1) Pioneered voice transmissions through electrical signals along wires, enabling live real-time conversation between remote parties.
2) Rapidly advanced after Alexander Graham Bell’s patent, leading to significant infrastructure installation over cities.
Radio Transmissions:
1) The concept of sending and receiving information through space using electromagnetism gained momentum.
2) Though largely experimental and less practical at the time, radio set the stage for wireless communication of the near future.
