In the words of a 2011 report from the Oxford School for the Study of Journalism and the Reuters Institute for the Study of Journalism, "Mainstream media is the lifeblood of topical social media conversations in the UK."[5] While the rise of digital media has disrupted traditional news outlets, many have adapted, and have begun to produce content that is designed to function on the web and be shared by social media users. The social media site Twitter is a major distributor of breaking news in traditional formats, and many Twitter users are media professionals. The function and value of Twitter in the distribution of news is a frequent topic of discussion and research in journalism.[6] User-generated content, social media blogging and citizen journalism have changed the nature of news content in recent years.[7] The company Narrative Science is now using artificial intelligence to produce news articles and interpret data.[8]
