I guess there are more than one channel head or creative head at SP.
So maybe 2 of the SP Creative Heads like saas bahu shows, only one likes thrillers.
So the 3rd one makes the other 2 agree to telecast a thriller like EHT.
2 months pass with the novelty show and the other 2 creatives tell the 3rd one ur show isnt getting good trps so change the script to shadi track, romance track etc.
3rd creative head tells PH to add wedding, romance, saas bahu etc. PH does that under coercion, trps pick up and show continues.
But 1st and 2nd creative have taken bribes from more famous PH to telecast their shows...so they deliberately pick up a fight with EHT ka PH and force them to end the show before their time is over.
The above is just a theory but it can just as well be true. A lot of these things happen in business world so why not in showbiz?
