From my perspective, as a leftist and not a liberal, I'd describe the BBC and NPR as having, largely, a liberal / centrist viewpoint. I don't think I've ever heard the BBC advocating seizing the means of production or NPR agitating for a general strike. If you are in the US, consider that our entire political compass is shifted very far to the right. In Europe, the Democrats would be considered a center-right party and the Republicans would be a far-right, borderline extremist party. Regardless of where you fall on this spectrum, it's important not to fool yourself into thinking you are in the "center" or have some "objective" viewpoint from which you can label things "left" and "right", when everything in politics is so contextual.
