I'm not in the US, but to my knowledge it's rare for British television to travel anymore. There's probably The Office, Extras, Top Gear, Dr. Who and...well, that's all I can think of.

My friend has been encouraging me to check some of them out via bittorrent. He speaks highly of Skins and a bunch of others. The selling point is that most seasons are much shorter than the 24 episode US Season arc so it's easy to start watching.

However, I must admit that I haven't looked at anything yet. With so many movies out there it's tough to start watching a television series especially when there's always the risk of cancellation.

you shouyld also check the "Mitchel and Web look".
It is a sketch show made by the same to lads.
Has some very good sketches in ti.
David Mitchel also appears on a lot of panel shows ie QI, Mock the week , Would I lie to you

We have "BBC America" on our cable system which gives us stuff like "Being Human", "The Graham Norton Show" and "Torchwood"...but then they also show stuff like "Star Trek: The Next Generation" reruns.

On PBS we also get one offs like the recent 3-episode "Sherlock" series.
