I specifically remember reading about the "research" regarding think tanks.
It was done at Stanford, and it compared and contrasted how often various media networks cite conservative vs. liberal think tanks, and compared this to how often these think tanks are cited in congress.
The concluded that Fox cited both liberal and conservative think tanks at about the same rate as congress, while the other networks cited liberal think tanks far more often than conservative ones, and at a disproportionate rate to how they are mentioned in congress.
Far be it from the Grey Lady to truthfully report what the "research" actually said...
Instead of reporting the fact that the research indicated that all the networks were far to the left of the mainstream and disproportionately cite liberal think tanks, they try to imply that the research indicated bias on Fox' part.
Someone should dig this one up...
Here is the research the Times is referring to:

Here is the conclusion of the research that the Times spins as indicative of Fox News' bias:
Although we expected to find that most media lean left, we were astounded by the degree. A norm among journalists is to present “both sides of the issue.” Consequently, while we expected members of Congress to cite primarily think tanks that are on the same side of the ideological spectrum as they are, we expected journalists to practice a much more balanced citation practice, even if the journalist’s own ideology opposed the think tanks that he or she is sometimes citing. This was not always the case. Most of the mainstream media outlets that we examined (ie all those besides Drudge Report and Fox News’ Special Report) were closer to the average Democrat in Congress than they were to the median member of the House.
