Today Programme: Britain's Most Influential News Show

It is credited with being the most influential programme on British radio. The Today Programme on Radio 4, the breakfast listening of choice for opinion formers and agenda-setters in politics, business and the media, and huge swathes of the professional middle-class, isn't just a flagship news show: it's an institution. If you were filling a time capsule representing layers of Britishness in 2011 for future generations, you'd want an edition of the programme in the mix.
