Guglielmo Marconi was usually credited as the inventor of radio.
He started working on wireless telegraphy in the 1890s. Numerous scientists had been exploring wireless telegraph technologies at that time.
Heinrich Hertz, in 1888 demonstrated that one could produce and detect electromagnetic waves, at the time commonly called ‘Hertzian’ waves and now generally referred to as radio waves. Marconi began pursuing the idea of building a wireless telegraphy system based on Hertzian waves (radio).
He made significant breakthrough on 13th May 1897 when he sent the world’s first-ever wireless communication over open sea. Marconi gained a patent on the system in 1896 and developed it into a commercial communication system.
Commercial radio broadcasting began in the 1920s and became an important mass medium for entertainment and news.
