Lets see if I can paint this picture.....You're familiar with Goggle Earth and how you can zoom into your own neighborhood etc.....

Now picture a typical magazine cover..Standard 8" x 10"

In the bottom R corner you see an ad for new automobile..The ad takes up 1" x 2" of the page...

I saw a demo of some future technology that showed how you could click on the auto ad and zoom in and see all of the specs/color choices/all the options etc......Zoom in some more and you could read the owners manual for the vehicle...

The kicker is that the size of the file is relatively small is size....
