In a media-based society (and of course there is no such thing as a non-media-based society consisting of more than one person) it is the signs and significants, the meanings and habits and conventions of speaking and thinking, the images and stereotypes which control everything. It is important to analyze how it is represented and of course what is not represented or how it lacks representation. It's not so much Rupert Murdoch – whose assholeness I will not dispute – that we should attack, but rather something I would call the cultural grammar of the public space. Power is formed within such a grammar. Access and non-access to each and every thing is regulated in its realm. Meanings are negotiated there.
