Are you familiar with the perturbed feedback systems?
Like electrical control circuits or evidently (but not trivially at all) the earth's atmosphere?
In a utopian world, where nobody wants to make anything but giving the audience what the audience want is a simple feedback system: the producer makes something, the audience gives a feedback, the producer make something that can satisfy that feedback and so on, till you reach an ideal equilibrium. It's like the body controlling yours blood beats when you start jogging: "raise it! A little higher. Too high, this rythm will faint you in a moment, try a bit lower. Lower again... too low, the muscles wants more oxigen try the half... you got it!".
In that world WE are the media.
In a real world the producer strive to give audience not only what they want but also try tu amuse the audience, they have to face that people get bored watching the same things, they have too face the fact that they don't wanna be part of the "equilibrium" they wanna rise over the other to make more profit, in the same time he have to face the budget guy and the marketing rep.
So he don't have to give the exact response to the feedback, sometimes his above his power (the producer doesn't have infinite money, and doesn't work for the sake of art) and below his expectations (he want to stand over the mass and beat the competition, not only be a part of that equilibrium), so try to put in the market a product he think will have success, in that way he perturbate the audience strive for equilibrium (like putting an obstacle to the jogging of our friend) and the feedback can be good or can be bad, can instill new ideas in the audience perturbating succesfully (convince the friend to stop or continue another way), or can be ignored and the audience will keep running over the same objective.
That kind of system, with a feedback, perturbed and so on, under some condition are called with the fancy and most known name of "Chaotic systems".
I hope I made my point, I can see it clearly in my mind but is something I studied and worked for a lot of time, and trying to explain it and to be crystal clear in foreign language is far more difficoult than I expected
