So on one hand the anti-BBC posters say there's nothing on but Wanted Down Under and Eastenders, on the other it's nothing but high culture. Pick a story, guys.
So all the different posters are supposed to pick a single story and stick with it?
The BBC's offerings are neither uniquely nor uniformly high-brow - so long as one has a smart TV, alternate options approach the infinite. The BBC has, in the past, made it possible for people to access culture, news and entertainment in an easy way but technology has long since crept in eroded the value of its offering.
You can make the case that there's value in a non-commercial news outlet, but this could be managed via a government grant and supplemented by voluntary public support like PBS or NPR in the US.
