Communication Technology in the Past

This exploration of communication technology traces its evolution from primitive methods like the visual and auditory use of alphorns and smoke horns to more sophisticated means such as the telegraph. The use of drum signals by Native American runners and the historic Pony Express showcases early long-distance communication. The invention of the telegraph revolutionized message transmission over vast distances using Morse code, marking a significant leap in communication capabilities since the late 1800s. Join us in understanding how these advancements shaped human connectivity.
