I was so confused by this when I saw which British TV shows were being broadcast in America, I lived there for a year as a 17 year old. Suddenly dated stereotypes and the general lack of awareness about contemporary British culture, accents, etc. made complete sense.

Even back then (about 17 years ago) the titles mentioned above were equivalent to the lowest tier cable re-runs on one of those retro TV channels that thrives on being cheap.
