GCSE History Cold War 1945-48 Revision Podcasts

This is for Teachers / Students that are studying GCSE History Cold War 1945-48.
I have done 7 podcasts that are formatted to play on PC and Mobile Phones.
I put these files on memory sticks and tell my students to revise from these and exercise.
Rather than sitting at a desk reading and writing, they can listen to the short presentations I have done by going for walks / sitting on the bus commuting to school and home / listening before going to sleep etc.
Podcasts include reviewing:

1. Background to the Cold War 1920s-40s relations between UK / USA / Soviet Union
2. Communism and Democracy Ideologies
3. Yalta Conference
4. Potsdam and Iron Curtain
5. Soviet Expansion of Communism in Eastern Europe
6. Reaction of USA to Communist Expansion 1947-48
7. Berlin Blockade and Outcomes 1948-49
