Let me just plop something else in here as we are on the subjects of bias, journalism standards, media manipulation, and 'culture capture', etc.
Administrations will famously toss out the bad news on a Friday night (avoiding the daily 6 o'clock news cycle, and giving time for damage control) or likewise, under cover of some larger event. An example was when the Blair administrator sent out a memo on Sept 11 advising that this would be a good time to get out any bad (for Blair) news.
Perhaps coincidental, but I doubt it, the story on the right wing columnist pundit who had been paid a quarter mill by the Education Department to hawk their story came out right at the same time as the independent commision report on the CBC fiasco. It's advantageous when you can use as a defence..."well, gosh, look over there!"
In any case, the Columbia Journalism Review did a report on a particular element of the CBC story...ie the role of the blog world in pointing out how the CBC story was weak and the documents undependable. It's a very good piece. I'll link it first, then the second link is to letters received in response to it. Talk about culture capture.
