Sesame Street doesn’t broadcast in the UK but they have a Sesame Street Podcast, it seems. I am a little concerned that according to iTunes, “listeners also subscribed to Abigail’s X Rated Teen Diary” (fortunately that programme isn’t what it sounds like).
I have to say that the sample I saw didn’t really impress me with the Sesame Street magic but I figure there must be some reason why it is the ‘gold standard’ for educational television in US studies.
