Television formats and individual programmes and series are formulated and dictated by public interest.
For the commercial channel, this depends entirely on audience numbers, which attract and drive advertising revenue, so their output is necessarily 'lowest common denominator' in large areas, to attract the largest numbers.
But the medium has always been driven by the wants of its audiences, and it always will, because that is how the system works.
The BBC, government funded, has the luxury of a more cerebral approach, and can offer output that is niche in appeal, but fulfills their charter remit to 'Educate, inform, and entertain'.
Television will remain viewer-led because that is the system that drives it, with no sign of changing anytime soon.
If enough people stop watching, a programme/series/format will be dropped/altered/ updated, depending on the ideas of the programme makers.
The only way to deal with this is simply be selective - enjoy the programmes you like, ignore the ones you don't.
You'll be using the system that drives television, and always has - if it's not popular, it won't stay.
