A number of start-ups are building businesses by organizing independent video makers to create online videos commercials for national brands. Like San Francisco-based TurnHere, which has organized a network of independent videographers to create editorial content, these start-ups are reaching out to independent video makers to make ads. This is not an open mash-up, but highly organized RFP's, assignments and sizable compensation in some cases. Adweek's Eleftheria Parpas wrote a round-up of this trend last week. Mark Walsh, best known in the last bubble as the founder of VerticalNet, has launched a company called Genius Rocket. (Check out this profile of Mark and VerticalNet see in Business Week from 2000. Also in the space is Brickfish. XLNTads.com is creating a network of hundreds of video graphers. It is about to launch an RFP for creative for a Nestle 100 Grand bar. I caught up with XLNT's Mark Schoenveld in San Francisco last month for the NewTeeVee conference. -- Andy PlesserPosted on Beet.TV on Sunday, December 9, 2007http://www.beet.tv/2007/12/user-generated.html
