I get 1 hour of BBC on my local PBS station, plus our international channel has the BBC for a few hours every day. I only have basic cable.

There are also 3 NPR stations on the radio in my listening area, and they all carry BBC reporting during the day; and if all else fails, there's news.bbc.co.uk (be sure to click that you ARE inside the UK when asked).

I like BBC as well, but I don't think accessibility has anything to do with their lack of saturation (at least where I live). I'd love to have 24 hour BBC (do they broadcast 24 hours?).
