As we all know, National Geographic has some of the world's best documentary films. Most of these documentaries are available for purchase on DVD. However, in these tough economic times school budgets may not allow for the purchase of all the films that you would like. If you're in this situation, there are two ways that you can view National Geographic videos online.
The National Geographic Channel's video page has hundreds of videos that you can browse through, watch, and embed into your own blog or website. Good news for readers outside of the US, most of these videos are available for viewing outside of the US. To view the videos outside of the US click the "outside the US?" link in the upper right had corner of the video page. The only drawback to the National Geographic Channel's video page is that it doesn't have a good search feature so you have to browse through a lot of videos to find what you want. Some of the videos are full-length documentaries and others are just short snippets of video.
Snag Films has become one of my favorite places to find full-length documentary films. Snag Films has a National Geographic section offering more than 60 full-length documentaries for free viewing. All of these videos can be watched on the Snag Films website or "snagged" and embedded into your blog or website.
