I work for one site that is small but is quite popular for people with no life and likes to spend most of their time looking at videos online at places such as flashplayer and newground... the guy I work for makes some claymation type videos that he sells on a dvd but also posts online. he's currently working on a full length movie that he plans on selling for about 20 dollers about plans on selling 10,000 copys .
But since he can't really pay me for the work I do I put a google ad on the site (adsense) and I make my money that way.
If you want to know check his site out at: www.knoxskorner.com
