Not sure they are killing it unless they make more from online subscription than cable. Lots of my friends and I have unsubscribed from cable and brought Hotstar subscription. So now they have to support multiple channels (online/cable) for a disjoint subscriber base. And it is only a matter of time when Netflixes, Facebooks and Amazons start bidding for live sports in India as well [1]
They are the leaders in this domain, thats what I meant by killing it Capturing customer base is the first step in any new venture's plans right? Not sure how they've planned their strategy but they streamed 25million concurrent connections during the super over in CWC.
If the big ones start bidding then we'll see how it goes. But for now, star is way ahead. Also 300million users when the country is making its transformation to fully mobile and VOD is massive!
