HBO certainly traded on some raunchy TV: Californication, Sopranos etc. GoT had raunch and nudity, but overall that trend feels like it peaked and is trailing off too.
It occurs to me that those shows are pre-Netflix. Netflix and the other video streaming platforms could be pushing for more family friendly content in general, and discouraging anything remotely like "porn" on their platform..
GoT is a great example of the evolution of raunch; explicit nudity and sex scenes were HBO's bread and butter for a while, especially obvious in S1 (even episode 1) of GoT.
But as it got successful - and the actors set boundaries - they realized the show didn't actually need it.
If sex scenes and nudity were a crutch to hide bad writing, I'm all for getting rid of it. Of course, you can have both.
