Extending a factual TV series or a documentary with additional digital content is nothing new. In the late nineties, the BBC developed some complementary content for its flagship documentaries accessible by red button technology. These offers were created around the concept of “click to know more”. They acted like extensions of the TV documentary, providing audiences with additional information around the subjects or characters featured in the documentary. More recently, the likes of Arte in Europe and the National Film Board of Canada have been co-producing this sort of “two-windows” documentary, where audiences can extend their TV experience with additional digital content made available on the web (or mobile platforms).
