Bringing up GoT is foolish
The era of big shows that everyone is talking about at the same time is over
GoT was the last one
Nah, whatever hour long drama HBO premieres in the fall will capture everyone's attention again.
The "formula" for creating a show that everyone talks about really isn't too complicated.
1: make sure the show is REALLY good.
2: dripfeed the content.
3: give it room to breath
The real difference between HBO and Netflix is really just volume. HBO essentially dedicates a fell 10-12 weeks to whatever their main Sunday show is at the time, and doesn't run anything else that fills that same lane until that show is over.
Netflix drops a full 10-13 episodes on you all at once, which automatically fukks up the everybody talks about it angle since not everyone is going to watch the episodes at the same pace. Then, they usually have another show or movie they hit you over the head with a week or two later based on you having watched the show from a couple weeks before. As a result, people forget about these shows quick.
