Suggestion to Listen to understand American History

It's ironic about my job and my interest. I had no interest in US or US history before I started my current job. While my job is so keen to the US history. So I started to find something to catch up. Lucklly, I found this audio casseets series: the century, published by ABC, hosted by Peter Jenneies. I do like it. Try it if you have some spart time to kill.
