One of the most interesting data I have come across in some time now.. is this chart telling us about the radio habits of people in different metros in India.
It is indeed an eye-opener for national planners.

The way, Bangalore seems to be consuming radio in the mornings and the way Kolkatta being the earliest riser of all is worth a thought. Not only that, Kolkatta also listens to radio a lot at night as well. Delhi and Mumbai are the lowest consumers overall which again is interesting.

Oh! I just so love radio :)
