No, it won’t shut down because it has several popular shows like Maharashtrachi Hasya Jatra and Kon Honaar Crorepati which have established Sony Marathi’s brand value.
On the contrary, I feel that Zee Yuva should shut down as there are far too many Marathi channels from Zee currently. Zee Vajwa already shut down but that was completely unacceptable since it was a unique music channel.
