Kaltura has cemented its place firmly on the Collaborative Media map, as the world’s first (legal) open source video platform. Promoting active collaboration, sharing and remixing amongst its users, the tools offered by this pioneering startup, boil down to 3 main strands. First, enrichment of video and rich-media features to existing sites; second, user-friendly creation of new open source communities; and third, ability to legally share and remix each and every last scrap of uploaded content – including the entire digitised archive of rare historical images from New York’s Public Library.
