I've found Yahoo video as a top video site on the net. Not only videos from their members but also from other video sites which are crawled. Amateur videos, movie clips, old cartoons. It can be a way for advertising. You make a video and you add the desired link. Any other good video-advertising opportunity?
To be frank, if you mail me your videos, i can add them to flash.vg. Attach them and send them to: Robert
