Radio dominated the first half of the 20th century but the advent of affordable TV sets in the 1950s seemed to spell doom for the format. Yet, radio endured. Radio was able to create a distinct image for itself, separate from TV. I have own theories as to why (cars, transistor radios and the music industry) but nothing conclusive.
It’s kind of a bonkers question because they are different technologies with different use cases only related in that they were both used for entertainment. It’s almost like “how did trains survive the invention of airplanes?” (or boats and planes).
