Seth Godin pointed out that there might be more than one YouTubes in the world, especially after NBC Universal launched their own form of video sharing. Instead of it being user generated content, this stuff is actually coming from the corporate folks themselves.
DotComedy is full of various clips of NBC programming, but I believe there are clips from other networks as well. For the most part, it operates a lot like YouTube. There is an embed function that is not working yet, and the “coming soon” doesn’t give much of a time line for when that will be operational. Still, it creates some competition for fans of YouTube, as long as the content is fresh.
Just looking around the site on my first time through, a Late Night with Conan O’Brian clip of “Satellite TV”, and this Double Dragon short was highly enlightening. Lord knows I wasted time on that game in my youth.
