On this day March 10th in 1876, the very first understandable speech was transmitted over the telephone. Alexander Graham Bell spoke through the telephone and told his assistant, “Mr. Watson, come here. I want you.” Just three days before this, on March 7th, Bell had received a patent for his telephone system. In 1877, Bell would found the Bell Telephone Company, a company that would later be bought by the American Telephone and Telegraph Company (AT&T).
