I do not understand where your logic is but I feel I need to point out this to you. You have an excellent show named Rangrasiya who has not been blessed with one brilliant actress but a perfectly worthy co star whose acting skills are impeccable. The show has everything you would need to create your channel to have much more success and much more money (since money is usually what many channels care about). So as a viewer I'm stunned by how you are not using the show to your advantage and even though I'm pretty sure you have a game plan, I wonder whether you will actually realise how flawed your plan is. I do not understand why you don't promote a show which can reel in much more viewers who may become a regular member of your channel and thus would that mean that your channel will remain popular.
I'm stunned that you are not wanting to grasp in many new audiences who may or may not contribute to your channel success.
I'm suprised that you think that by neglecting the promotion of the show that viewers may forget about it and may move on.
I'm wondering how Rangrasiya which has managed to gain international success isn't your priority at the moment. Why would you not want to work on that and make your channel thrive more internationally?
And lastly I hope you do realise that this neglecting, this lack of balance in the promotion of ALL your shows is actually causing you damage in the future. Why would people tune into a channel knowing full well that they don't treat their shows properly?
Please learn from other channels mistakes and do not do this to yourself.
Thank you and goodbye.
