In the late 1800s, the invention of the telephone revolutionized communication. Alexander Graham Bell, an inventor and teacher, was the first to secure a patent for the device in 1876. His innovation allowed people to communicate over long distances instantly. Prior to the telephone, communication methods were limited to letters or face-to-face conversations, which often took days or even weeks. The telephone's success led to the establishment of telephone companies, which expanded the network further. Bell's work didn't stop with the telephone; he continued to invent and improve technology, notably contributing to the development of sound recording and airplane technology.
