About
Radio transmission of electromagnetic waves enabled wireless communication that transformed news, entertainment, military operations, and safety. Guglielmo Marconi transmitted the first transatlantic radio signal in 1901; within 20 years, broadcast radio was delivering news and entertainment into homes worldwide.
Radio was the first mass broadcast medium — preceding television by decades — and created the concept of simultaneous mass communication. Its role in wartime (enemy communications, propaganda, navigation) was decisive. Radio astronomy, using the same electromagnetic spectrum, has made some of the greatest discoveries in astrophysics, including the detection of pulsars and the cosmic microwave background.
