I'm currently reading an excellent book called "The Guardians Of Power",
http://www.medialens.org/bookshop/guardians_of_power.php
It's written by the guys at Media Lens,

It's primarily concerned with foreign policy and the media's, including the so called impartial BBCs, reporting. I think a lot of the arguments could equally be applied to their reporting on the housing market. The thrust of the book covers your point right_freds_dead - "i certainly dont feel its as independent as it should be". The book contains correspondence between the authors and key mainstream journalists. They argue that there doesn't need to be a national media conspiracy.,....
"What Andrew Marr, like others, 'doesn't get' is that dissident arguments do not depend on conspiratorial self-censorship, but on a filter system maintained by free market forces - bottom-line pressures, owner influence, parent company goals and sensitivities, advertiser needs, business friendly government influence and corporate PR 'flak' - which introduce bias by marginalising alternatives, providing incentives to conform and costs for failure to conform"
Chomsky - "I don't say you're self censoring. I'm sure you believe everything you're saying. But what I'm saying is, if yo believed something different you wouldn't be sitting where you're sitting"
Although these comments are written in relation to foreign policy I'm sure many of these arguments hold across each section of the paper, including property. It's the VI stuff we see.
Sorry if I've gone off on one here but reading the book has made by tube journeys fly by and it helps me interpret what would otherwise be frustrating stories
