I guess after long time Star Suvarna got good host. Decades back started with PHHL kiccha Sudeep, Swayamwara Rakshitha, Kotyadipathi Puneet and within few months became No.1 position for few years. After that it was not able to sustain market for longer time, due BBoss Sudeep shifted to ETV.
Bringing people from Big screen to Small screen will really work to gain attention and TRP. ZEE knows this fact and that's why it has good combination of film artists like Umashree, Vinaya Prasad, Anirudh etc.
The channel should telecast reality show 30 mins before it's competitors like how Zee shifted to 7.30pm slot instead of standard 8pm before.
Moral of the story, "when new viewers can't be added, should try to retain from its competitors" whenever they are weak. Just revamping the slot again and again won't work unless competition is weak.
