Some facts Taarzan got popular among kids audience. It was earlier with zee and it was also made popular by Zee inly but now Star has it and Star has done a far more superior job than Zee. Ajay Devgn has his deal continuing with Star because of Baba Arts goodwill. baba arts also dubbed dhruva in hindi. also Ishq (another Baba Arts hit on TV) gained more coverage on Star rather than on Zee (where it was shown as a prime time movie) Network change too has a role in making movies popular taarzan is a good example of that.
Well these were popular on Zee too, interchanging of movie rights is a common practice in Hindi Movie Genre on TV. I can give u long history of that but anyways Star India is building up on hindi movies post Disney takeover and a good thing to happen. Right now Star India has too much repetition across channels and it tends to become boring.
I think output deal concept which is there in English Movie Channels should be adopted in Hindi Movie Channels too. Just have first output deal for limited 0period and then leave it for others. This way one can avoid spending huge amount on exclusive long term deals and acquire more content to let refreshed appeal continue
