FX, Fox Crime were not doing well interms of ratings even when it aired different shows including new ones hence it was decided to shut it down and gradually its content was downsized . Though as i have said earlier that erstwhile Star India under Fox should have continued both the channels, if not both then atleast FX
About Star Sports Select HD channels exclusive strategy for Football, i have already discussed in detail why it was a flawed strategy and what promoted Star India to take such a decision. Similar was the case when they launched Star World Premiere HD and removed most ofvthe popular shows from Star World which ked to the latter's downfall. To b short they wanted increase in subscription revenue for niche content which in India won't work for linear satellite channels and a channel needs to available affordable price with regular advertising for it to remain viable.
Right now there is no such strategy being implemented incase of Star World or Star World Premiere. Basically they had decided to shut these down earlier but as they have not launched NTO 2.0 compliant RIO yet hence task of shutting down a channel and launching a new channel in another genre cannot be done right now bcoz it requires changes in genre placement of certain channels which will be shut down and new channel will take its place which is not allowed in NTO 1.0 RIO
They may as well be reconsidering the decision to shut down Star World and quite possible that it will continue with a revamped strategy. As we have seen that earlier changes announced for UTV Movies, UTV Action, Disney International HD, Bindass, Disney Junior, Star Utsav Movies now stand cancelled as one can see that name changes of licences which were earlier visible in MIB permitted channels list are now back to old name
