Youtube allows you to upload videos to their site and share them with whomever you want.
Whether you want to show videos just to your family or demonstrate your talents as a director, Youtube makes it simple.

Youtube allows you to share videos on other sites like Xomba and Myspace. All you have to do is copy and paste the Embeded Code that is along the right side of the video.

You can even create a user account and leave comments on peoples videos.

Youtube was sold to Google in 2006.
