A Brief History of Audio and Video Technology Development

This timeline chronicles pivotal moments in the evolution of audio and video technology from the first recording in 1860 made by Edouard-Leon Scott de Martinville to the advent of MP3 players and digital music stores in the early 2000s. Key milestones include the invention of the moving-coil transducer, Thomas Edison's creation of the talking movie, advancements in radio technology by RCA and Zenith, and the introduction of CDs and MP3 players. Each innovation laid the groundwork for the modern audio-video landscape we enjoy today.
