Actually there is a book version as well:<p><a href="http://www.amazon.com/Connections-James-Burke/dp/0743299558" rel="nofollow">http://www.amazon.com/Connections-James-Burke/dp/0743299558</a><p>I loved this series as a kid.  It was my favorite TV show.  Now that I know more about the history of technology, the connections sometimes seem a bit strained, but even so I know of no better introduction to the topic.
