The wonder of iPlayer means I can watch the best of the Beeb without needing a television. I highly recommend The Genius of Design. It’s a lightweight look at the design trends of the 20th century, highlighting certain key designs and movements, but still full of interesting new stuff for an interested non-expert such as I. The episodes that are up so far are available until 11th/12th of June, which suggests another two episodes are left in the series.
