People seems to left television programs while they are on the journey on the road with car.
Why not a television company make a specific radio for a television. A specific frequency radio for specific television channel. By this, not only their marketing is further, but their network are also better
Stories also are not missed.
A news television channel like Astro Awani, Al-Jazeera, CNN and BBC should take this idea to further broadcast their news to a broader listener.
In poorer country, radio is more available to be heard compare to television and for a blind person, this will be advantages for them.
The conclusion is, the same exact sound comeout from television should be made into a radio channel.
