Amazingly to me, it has already been a year since YouTube was purchased by Google and to celebrate that anniversary, TechCrunch decided to take a look at all of its competition.

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.

Since they are all about 80% the same, I’m not going to go through each of them one-by-one at length. However, there are some overall trends that ought to be pointed out, as well as some key differentiators.

They take a very interesting look at the video sharing sites, and show off their video interfaces. Should YouTube be worried? TechCrunch enjoys Blip.tv. I, personally, enjoy Stage6’s DivX platform.
