Visual analytics helps analytical reasoning and exploration of complex systems, for which it combines the means of interactive visualization, with the power of data analytics. The recent progress in computer vision techniques opens wide applications in real world video archives. Particularly, recent advances in face detection and recognition have been put under the spotlight. The applications of such techniques are often concern intelligence, or peer recognition in photo posted in social networks. We propose to combine those two domains by demonstrating a visual exploration of over a decade of the news program from the Japanese broadcaster NHK News 7. We derive social networks from face detection and tracking of this large dataset. With the help of a little domain knowledge, we monitor the activity of political public figures and explore the archive. This allows understanding and comparison of the politico-media scene presented by NHK under different Prime Minister's gover-nance. The social networks are interactive, and to explore the multimedia database and its video content.
