Technology The Birth of Wireless Communication
Guglielmo Marconi didn't invent radio, but he commercialized it. In 1901, he transmitted the first wireless signal across the Atlantic Ocean, sending the letter 'S' in Morse code from England to Canada. Many physicists believed this was impossible because radio waves travel in straight lines and Earth is curved. Marconi succeeded because radio waves can bounce off the ionosphere.
