War(s) of the World(s)? (E05)

In the final episode of her epic journey across history, Cunk takes us from 1945 to the present day. She travels the world and meets top experts to examine the Cold War, the space race, globalisation and social media. The world's recent history is one of polarisation and division, as humanity divided itself down the middle – communism v capitalism, Apple v Microsoft, Beatles v Stones. Is humanity doomed to repeat the mistakes of history? Cunk does her best to find out. (BBC iPlayer)
