Yes but in small markets like gujrati, punjabi, bhojpuri they should not launch this channel, audio feed is sufficient for them as people from this region are also ok with Hindi/English and if their mother tongue is there then ok for them.
They should launch ETV bal bharat in Big 6 language markets that is Marathi, Bengali and other 4 south markets.
I don't think launching separate channels in languages like gujrati, punjabi, bhojpuri which are very less watched will help them! Audio feed is Enough for this languages.
