I don't doubt it. It's true of pretty much 99% of the media in general. Ditto for history in general, too.
Once you're out of touch with truth on even one point, you'll miss the boat on lots of other things, too. Needless to say, anytime I look at anything in the mainstream media, I keep this in mind. My "fascination" with the history channel, for instance, extends chiefly to things they can't really mess up like... "how carpeting is made." Or my visits to a certain archaeology site (more lies than truth, probably) to simply see/read about what was found, and draw the conclusions for myself.
Ah well... some people do crossword puzzles to waste time when bored. I look at things like that.
