Now, today iPlayer does a fine job of satisfying the time-shifted desires created by the scheduler: the BBC schedulers create the desire to watch a programme; iPlayer lets you see it at a time that's convenient to you.
But what if you no longer watched linear TV? Who becomes the tastemaker then? Right now this is a largely theoretical problem as very few people watch no live TV at all. However, for a small but growing number of people this is indeed the case, and the fundamental problem that I sought to address was "who becomes the tastemaker for such people in a world without schedules?"
