I've had arguments with you long ago where you failed to grasp even the tiniest logical reason. I said Hotstar will lose 15-20 million subscribers when they lose IPL rights.
We are in 2024 and Hotstar lost more than 20 million subscribers. So who lacks knowledge here?
Also, the strategy you're talking about won't make sense if you spend 10-20 mins with an Advertising executive.
If JioCinema executive thinks they can attract bottom, mid and top then they're as clueless as you are. JioCinema should at least figure out their local programming like how Prime Video India did in the last 3-5 years.
If the subscription revenue was meaningful, they would've disclosed the number of subscribers the service attracted since launch. I assume they are very minuscule and it will stay that way as long as they don't invest in local programming.
HBO and other international programming won't move the needle much.
As for the advertising revenue that comes through sports, it is the only positive thing to come out of this service. And this works as long as it is not behind a paywall.
You're the one with lack of knowledge and how streaming strategy works.
