The main idea is that the telegraph made messages travel as electrical signals over wires, which could be sent and read far more quickly than any handwritten note carried by horse or ship. Messages were encoded into signals—later standardized as Morse code—so letters and words could be transmitted and decoded at distant points in near real time. This capability transformed how business, government, and news operated, allowing rapid coordination, scheduling, and decision-making across long distances. It wasn’t about replacing all written correspondence, nor about voice communication (that came later with the telephone). It did, however, have a major impact on national and commercial expansion by enabling quicker, coordinated action across regions.
