Ad targeting solutions provider Visible World has raised a large $25 million hird round , according to Mediapost. Adams Street Partners and Alliance Bernstein led the round with their first investments in the New York-based company. Previous backers Comcast (NSDQ: CMCSA) Interactive Capital, Dawntreader Ventures, Grey Ventures, Leucadia National, Marketing Services Risk Surety, Time Warner (NYSE: TWX) and Viacom (NYSE: VIA) also participated in the round. Visible World raised an $8 million second round back on 2003.

Founded about eight years ago, Visible World’s main product is its IntelliSpot system, which creates custom TV spots tailored for specific segments of cable subscribers but it has been expanding beyond its initial cable focus. Last year, it developed a broadband and wireless division and began working with DoubleClick on a solution called Dynamic Video, which combines interactive design, ad-serving and reporting capabilities to support online video ads.
