Does the mainstream media have a liberal or conservative bias?

In the U.S? Establishment (and as such rather right-wing) liberal for the most part.

In the U.K the (national) private media is (with the exceptions of the liberal-to-social democratic Guardian, the centrist-to-fake left Independent and the working class populist (Labour Right would be the most accurate description o/c, but that doesn't translate well into U.S terminology) Daily Mirror) right-wing, but not really in a monolithic sense (examples; The Times, the Daily Torygraph, the Daily Mail and the Sun are all right wing, but are all politically quite different despite that). Local (private) media varies a great deal. The BBC is mostly Establishment liberal (though not as right-wing in this respect as the mainstream media in the U.S), but there's much more variety within it than is generally realised. The news on Channel Four is quite like the Guardian really.

It reflects the interests of its owners and their political allies.  So in the american sense that could be either 'liberal' or 'conservative', since those ideologies both favour those interests.  In practice however, even in the narrow american sense, they do favour 'conservative' groups such as the Republican Party.

Opebo is actually correct here.
