Any story that are being watched by public should be designed in such a way that they should send a beautiful message to the public and inspire them to do goos to the society.
Sumit this a very good topic that you have put for discussion.
Well TV is just a tool for entertainment and upgrading knowledge. It all depends on individual using it.
You rightly mentioned one thing is that, some contents are just put up by producers to earn higher TRP. TRP depends on viewership that is people like us watching the particular programme. So indirectly it is in our hands to make the programme popular by viewing it or not.
So next time you see some irrelevant news broadcasted by a particular news channel which continuously does so, just programme that channel to skip or child lock mode for one month. So whenever you surf the TV channels the skipped channel will not appear on your TV set. This will automatically reduce viewership of atleast one person that is you. If many of us adopt this technique who find a particular channel irrelevant the TRP will reduce and the channel broadcaster will realise that such broadcasting is only going to reduce his channel's TRP and will surely improve the content next time.

The TV Channels have their own commercial interest to pursue which do trivialise current important issues but the viewers too are responsible to a great extent.Now we have the freedom of choice it just one flick of the remote to switch channels.
