Who Really Invented the Radio

The video explores the complex history of radio invention, highlighting the contributions of Guglielmo Marconi and Nikola Tesla. It delves into early electromagnetic discoveries by Oersted, Faraday, and Henry, which laid the groundwork for radio technology. Tesla's innovations in wireless power and radio waves are discussed, along with Marconi's successful trans-Atlantic message and Nobel Prize. The narrative underscores the challenges Tesla faced in gaining recognition due to Marconi's commercial success.
