If you have an interest in the history of how the internet as we know it got started, the series "Download: The True Story of the Internet" is a very interesting look at the internet's history. The series has four episodes: Browser Wars, Search, Bubble, and People Power.
The series does a great job of keeping things interesting while covering the key people and key points of the internet's history. Although this series does not cover the latest in the internet since it was released in 2008, the history of how we got to where the internet is now is fascinating.
