I believe there's a massive market for it, especially in this day and age. People absolutely adore drama and a good expose; they can't get enough of it — myself included.
It taps into a very voyeuristic part of our personalities where we enjoy seeing the double lives that people are living and the corruption behind the scenes. Honestly, I believe the real problem is that modern media networks are absolutely shit at marketing it and don't know their demographics or how to drive interest.
Who doesn't love a good mystery, some intrigue, and drama? They're sitting on gold but are too scared to rock the boat with their corporate partners and are also so antiquated in their views that it's caused a complete disconnect from the average life in modern society.
The fact that so many executives and marketing teams continue to exhibit failure after failure with mainstream products because they're attempting to appeal to a very niche activist crowd on social media only demonstrates how separated they are from what people actually want.
