South Indians don't watch Hindi much. They love to watch their own language. When I go down to blore, I will hv to forget Hindi serial. My mom used watch only kannada. In case I switch to Hindi channel, she used simply go out from there. So, I cannot watch hindi when I go down india.
I know most of the SIs don't watch Hindi shows... movies they watch very few.
Even when I go to Hyderabad... it's the same scenario.
But their audience is more loyal and big in numbers if you compare that with Hindi show audiences. Din bhar sirf TV shows dekhte hai đ
