Here is a new name in Web video, Democracy, which is an open-source, free platform for Internet TV.
This site functions as an RSS aggregator, a technology that allows you to subscribe to video blogs or other video feeds. You can create your own TV channel of videos you find, and make it available to the rest of the world.
There is even a channel guide for the more than 1,000 Internet channels and "vlogs" that are available.
The site is run by a non-profit, the Participatory Culture Foundation, which aims to put the power of television in the hands of individuals.
