What have OTT platforms made possible for regular Indian audiences since 2016, which wasn’t the case in the decades before? Binge-watching shows? Not quite. 
Desis were spending about four hours, daily, on TV—watching serials, what else, that ran for hundreds/thousands of episodes anyway! There’s the near-unlimited access to film libraries, surely? But movies first belong to theatres — always have; always will.

What the OTTs heralded, and that should only grow with time, is a bunch of genres that network TV didn’t think was ‘mainstream’ enough. Free-to-access Internet would’ve rendered it amateur altogether. And it’s stuff that cinemas had no space for.
