NY Review of Books tends to hit from the left, but this very long and thorough piece feels much more cut-and-dry in its approach, going into incredible detail on the flaws and problems of this industry that's essentially become the entire focus of the media.
My favorite demonstrating how utterly reliable polls can be:
In an experiment conducted in 1980, people were asked whether they thought “the 1975 Public Affairs Act” should be repealed: a third gave an opinion, even though the act does not exist. In 1995 The Washington Post replicated the study with similar results, but found that another tenth could be goaded into an opinion with a follow-up question. (“Which [stance] comes closest to the way you feel?”) When people were told that either President Clinton or the Republicans wanted to repeal the act, more than half of respondents had a view. More recently, a UK poll found that nearly half of respondents claimed an opinion on a nonexistent politician, who actually proved relatively popular. (Anyone who has knowingly nodded along to a name they’ve never heard, hoping to avoid embarrassment, can relate to this.)
Anyway, it's a long piece -- probably a ten or fifteen minute read -- but well worth it.
