Who invented the radio and when?

The invention of the radio is credited to Guglielmo Marconi, an Italian inventor, who first demonstrated the ability to send wireless signals over long distances in 1895. Marconi built upon the work of other scientists, such as Heinrich Hertz, who demonstrated the existence of electromagnetic waves, and Nikola Tesla, who made early contributions to radio technology. Marconi’s breakthrough came when he successfully transmitted the first transatlantic wireless communication in 1901. His work led to the development of radio as a means of communication, and by the early 20th century, radio broadcasts became widely used for news, entertainment, and communication.
