Radio days were a time a long time ago when people didn't have TVs or phones to listen to music or news. Instead, they had radios that looked like big boxes with buttons and knobs. People used to gather around these radios during specific hours of the day to listen to stories, music, and news being broadcasted through the airwaves. It was like people could magically hear talking and music coming out of the radio! The radio stations would play a lot of different types of shows, like comedies, dramas, and even mysteries. It was similar to watching TV, but you just had to imagine everything in your mind. It was a really fun way to listen to stories and learn about what was happening in the world.
