Comcast Interactive Capital and Turner Broadcasting invested in Atlanta-based startup ViTrue, which provides technology to enable user-generated advertising campaigns.

As part of the “single-digit millions” investment, Comcast and Turner gain spots on ViTrue’s board, the companies said Tuesday in a statement. Former Tandberg Television President Reggie Bradford founded ViTrue.

Turner and Comcast also invested jointly in video-sharing site Revver earlier this year. ViTrue will put the cash towards technology investments and partnerships with brands and advertisers.
