An now, for the occasional non-political post on an unimportant (but interesting) subject:
I've seen three versions of the genealogy documentary series "Who Do You Think You Are": I've seen all the episodes of the Israeli version, the first season of the American version, and just one episode of the original BBC series. That one episode of the British show was about Kim Cattrall and her search for her long-lost grandfather, who had abandoned his family when her mother was a young child.
A few days ago, the American version returned to NBC for an 8-episode second season. Interestingly, Kim Cattrall is one of the subjects of this season, and according to Executive Producer Lisa Kudrow's description of Cattrall's story, it looks like they're just re-airing the two-year old episode from the BBC. My guess is that they're going to do some editing, like replacing the British narrator with an American one, and making a slightly more emotional, commercial version than the drier, more strictly documentary-like British origin.
It seems odd to me that the show is recycling an episode from the British version and claiming it as an episode of the new version. Why not announce: "And here, between seasons of the NBC show, let's show you a few episodes from the original BBC series of interest for Americans."
