A University of Edinburgh study, supported by the Engineering and Physical Sciences Research Council, found that news agencies continue to have an edge over Twitter in breaking news first. Over an 11-week period, researchers compared millions of tweets to the output from major news websites. The study found that the mainstream media often reported major breaking news before it appeared on Twitter. Twitter, however, did outperform traditional news sources with sports-related news and disasters where there were eyewitnesses at an event. The site also provided a large amount of minor local news items not covered by the mainstream media.
