What was the greatest change that Samuel F.B. Morse's invention of the telegraph brought to communication?

Samuel F.B. Morse's invention of the telegraph revolutionized communication by enabling near-instantaneous transmission of messages over long distances. This drastically reduced the time required to convey information, allowing for real-time communication between cities and countries. It transformed industries, facilitated faster business transactions, and enhanced coordination in various sectors, including transportation and military operations. Ultimately, the telegraph laid the groundwork for modern communication technologies.
