You can tell that's the case because practically every piece of music created has been put on youtube while nobody puts tv/movies on youtube for free.
So your spotify equivalent for tv/movies is going to cost $100+ a month, perhaps more because tv/movies are that much more expensive to make and that's what you were paying for cable back in the day.
But people think everything could cost $20 at most, so that's why we're going to have 10 or so streaming services and frankly that's way better than the old cable days.
