I have not been to it recently, but the How Stuff Works website was always an interesting place to visit. I came across a link that took me to a quick video on how Google Earth works and noticing the address, it was to How Stuff Works. Now, it seems that HSW has a video piece to it and the look is much different. I would recommend you check out this site
Here is the direct link to the Google Earth Video

*There seems to be a few more ads than I remember. That is the "price" we pay for a great free resource. :)
