In 2009, World Wide Web inventor Tim Berners-Lee stood in front of the TED Conference and made a call for 'Raw Data Now' - asking data holders to put their information on the web in accessible and open formats, rather than keeping it locked away in internal systems, or only publishing summaries in report.

One year on, 'raw data' had started flowing from some of the worlds largest governments and institutions, and from many small institutions as well. In the video below Berners-Lee updates the TED Conference on how open data is developing.
