For some years now I have been watching society (and not just British or American, either) moving inexorably towards a preference of presentation over content; in other words, it's not what you say that gets attention, but how you say it; not what you do, but what you are/how you look.

We've seen it in music, where M.Jackson's moonwalk and crotch-grabbing became more important than his voice and the Thriller video (brilliant though it is) more important that the song it purports to support. In fashions and in politics (OK, perhaps it was always there in the latter); and in Political Correctness, where it's what you say that is criticised, not what you mean or how you mean it - the letter, not the spirit.

Any other examples of the rise of Presentation over Content?
