Isn't YouTube for Teenagers?
Even if you've never visited YouTube before, you've probably read or heard about it. It's the web site on which a fictional character named "Lonelygirl15" became an internet sensation and where hundreds of thousands of people went to watch a guy scream, "Leave Britney alone!" while crying under a blanket. However, YouTube also contains a treasure trove of primary-source historical video for those teaching the history of anywhere in the world from the invention of motion pictures about 110 years ago up to the present.
