I've noticed similar events also.  It suggests to be a blend of both the media leading the government, but also government/business, or rather specific individuals in the government/industries, leading the media, in my opinion.

It seems that decision makers/elected officials, do not wish to actually do anything until they find out about it in the media after it causes an uproar (much like the Cons with the CBC RBC TFWs articles), where they then contact various outlet to state how they're working on a solution, essentially being forced to do their jobs.  But it also suggests that there are people who know this and give leads to the media, (or perhaps a sweetheart deal with regards to funding should they report on specific subjects?) who then manipulate the media to then influence the government into action to suit their own goals.
