Stage6.com is a high quality streamed video sharing website where users can upload, share and view video clips. In June 2008, CNET hailed Stage6 as one of the greatest defunct websites in history. Its has really good video quality and its only downside is downloading the divx plugin to play the videos. However, Stage6, which in January 2008 had 10.7 million views, announced that it would shut down(check the screenshot) on February 28, 2008. On February 29, 2008, a day later than announced, Stage6 was reduced to its frontpage and suggested that the userbase should migrate to Veoh, another video sharing service allowing high-quality uploads.
Screen quality appears to be the best with Viddler and Vimeo, and actually the second-worst for Veoh, better only than youtube.
