Since Netflix refuses to release its data, we can only guess what are the most-watched shows on the streaming service. Ditto most of its other competitors such as Hulu and Amazon Prime. And so, whenever a Parrot Analytics proprietary comes out with its own data and estimates, attention must be paid because, quite frankly, it's the only source we have. However, here's a surprise: a "Demand Expressions" metric shows that the Netflix hit "Stranger Things" was the most watched series on streaming in the last 90 days. The show is proving to be a monster. [via IndieWire].
