I had to drill down several levels to find the source for this oft-forwarded (and recently updated) chart, but it was worth it, both to see where it came from and to look at some of the reasoning that went into it (the author has a good multiple-part article starting here: http://www.allgeneralizationsarefalse.com/why-measuring-political-bias-is-so-hard-and-how-we-can-do-it-anyway-the-media-bias-chart-horizontal-axis/).
(Note that this is focused on US news outlets, with a few foreign outlets evaluated based on their US news coverage.)
Everyone will likely find something on here they disagree with (the author also notes that a given outlet's reporting often ranges around the background circles and elipses, so consider that before saying "X is far more liberal/conservative than that!). Your Mileage May Vary. But for myself, I'm pretty okay with it; the outlets I use in my own reading and analysis — and the ones I stay away from — are pretty much where I'd put them.
It also confirms one practice I have: if something strikes me as interesting or enraging or worth repeating, and it's from a source further to the either side or the bottom, then I look for info from a source further up/center, for additional information, confirmation, or different analysis. Daily Kos sometimes inspires me, but I very rarely quote it directly.
The other thing I find useful here is fodder for new places to read. I'll admit to my own bias in what sources I tend to go to, but increasing the quantity and looking for a few sources a bit further right than I currently read, at least to take a gander at them, helps keep me honest.

For those looking for a different view of this, the attached article includes the version that Alex Jones of Infowars (the guy pretty deservedly in the bottom right corner) came up with. Not surprising, one of his axes is "Tyranny vs Freedom".

when I see a story I am interested in I like to try to go back to the original source
I like to refer to this source when a story sounds wacky.

+Dave Hill Funny how Alex Jones' chart replaced the truth/accuracy axis entirely.
I know there are radical and totally unfactual liberal sites, but I just want to point out that of the inaccurate liberal sites, 5 are "news" sites versus 11 conservative sites. at worst the liberal sites have a very proliberal spin but aren't outright lying like the very oft quoted conservative sites.
