Let's start off with my own country:
Newspapers:
The Guardian - Left-of-centre in a metropolitan middle-class kind of way. Very socially liberal.
The Daily Mail - Right-wing populist with the occasional hint of outright fascism.
The Daily Telegraph - Essentially the thoughts and feelings of those on the mainstream Tory right.
The Independent - Centrist liberalism.
The Daily Express - Conspiratorially right-wing. Rambles on about the EU too often for even Nigel Farage.
The Daily Mirror - The paper of the Labour Party mainstream (well, the little news that's written in it anyway).
The Times - Mainstream right-of centre with (I think) some mild Euroscepticism thrown in.
The Sun - Populist in an even more stupid way than the
Mail. Usually backs whichever party is leading in the polls at election time.
Financial Times - Pro-European right-of-centre (though probably would be considered centre or centre-left in the U.S. as it endorsed Obama twice).
Television/Internet:
BBC - It's often fiercely debated as to whether it's impartial or not and if not where it does stand, but it's probably fair to say that it's (to echo Andrew Marr) culturally liberal.
ITV - Pretty impartial with perhaps a rightward tilt in recent years.
Sky News - Often labeled as our answer to Fox News, but really it's more our centre-right answer to CNN.
Feel free to list the outlets (and their respective biases) of other countries.
