Radio is the wireless transmission of signals, by modulation of electromagnetic waves with frequencies below those of light. Many of radio's early uses were maritime, for sending telegraphic messages using Morse code between ships and land. The radio was invented by Nikola Tesla. The radio was promoted and popularized by Guglielmo Marconi in 1895. The first radio transmission across an ocean (the Atlantic Ocean) occurred on December 12, 1901.
