Another great TV series from British islands. I wouldn't call myself a huge fan of British movies or series, but there are few really good one. And Mr Selfridge is one of it.

The story is about an American entrepreneur who founded Selfridges store in London, United Kingdom back in 1909. 

Here is more from Wikipedia:

Mr Selfridge is a British period television drama series about Harry Gordon Selfridge and his London department store Selfridge & Co, co-produced by ITV Studios and Masterpiece/WGBH for broadcast on ITV and PBS. The series began airing on 6 January 2013 in the United Kingdom (10 episodes), and on 31 March 2013 in the United States (8 episodes, the first and last being double-length). http://en.wikipedia.org/wiki/Mr_Selfridge

So far - have seen just first series, and all of them was worth watching.
