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.
They are two different offerings. I listen to a lot of radio and I watch television too. For instance, radio is great for concerts (letting your fantasy run with the music), or listening to while you work. For tv you need to sit down and can’t really do much else, the experience is much more intense.
oh yeah I forgot I had plenty of jobs where we had a radio playing in the background.
