News Corp reader revenues

With News Corp's decision to pull its papers out of the circulation audit this week, it is once again speaking with a forked tongue when it comes to the measurement of newspapers and magazines. Just look at what the three main arms of the Murdoch family controlled company are doing in their three main markets -- the US, UK and Australia.

News' decision follows the withdrawal of most magazine publishers from the Audited Media Association of Australia measure last year, and Fairfax withdrawing its digital data as well. And it means that while their publications call for transparency and disclosure from business, government, unions, universities and charities, they're cutting disclosure of their own.
