Netherlands Institute for Sound and Vision
The 27th of October was World Day for Audiovisual Heritage, an UNESCO initiative to celebrate and recognize the value of audiovisual collections for future generations. In light of this day Sound and Vision organized a “video-sprint” to encourage the use of video in articles on Wikipedia. The sprint lasted one week, from the 27th of October untill the 3rd of November. The result was that almost 200 new video's from their collections got used in articles on Wikipedia. Next year this day could possibly be used to organize an international video challenge.
