It's because of IPL and rural user dropoff during 8.30pm to 9.30pm. Earlier NM was holding those Rural viewers to switch on to Suvarna channel by 8pm. But now as LN is getting telecasted for 1hr, viewers shifted to Zee again.
NM in initial days had grabbed viewers from GattiMela, and slowly they went back.
Again with Janaki Samsara, it might get good TVR.
Plus point of Janaki Samsara
1. Kulavadhu and Helu hogu karana promo Hero after long gap in Kannada
2. Krishna Rukmini Heroine after a very long gap
3. Kavya Shastri in negative role for first time. (Hope she won't quit the show in between, not reliable)
4. Ashwini Nakshatra & many ETV serials fame Ammamma.
5. Marali manasagide fame Mother In Law
6. Namma Lacchi fame daughter & many more senior experienced actors in one serial.
