Alexander Graham Bell was awarded the first patent for the telephone in 1876 after experimenting with transmitting speech electromagnetically. While several inventors contributed pioneering work on voice transmission by wire, Bell succeeded in transmitting the first intelligible telephone call by saying "Mr. Watson, come here." Bell went on to form The Bell Company to commercialize the telephone, which became the American Telephone and Telegraph Company (AT&T) after building the first long-distance telephone line. The telephone became a crucial communication tool during World War 2 and has since evolved into modern mobile phones.
