From the Tech Crunch page:

Even if YouTube remains the destination of choice for the vast majority of consumers, producers ought to take a serious look at the alternative services. They often support more file types, bigger uploads, and higher resolutions. They also place fewer restrictions and provide an array of features simply overlooked by YouTube. That said, a few of these services are mere YouTube clones and hope to follow in YouTube’s footsteps by providing very basic features.

These are the services we looked at: blip.tv, Brightcove.tv, ClipShack, Crackle, DailyMotion, Sony eyeVio, Google Video, Megavideo, Metacafe, Motionbox, Revver, Spike (ifilm), Stage6, Veoh, Viddler, Vimeo, Yahoo Video, and YouTube.
