Collaborative citizen journalism (CCJ), a concept made possible by the Internet and the advent of blogging, is the pooling of research and reporting by volunteers to develop journalistic news storeys or to critically examine existing ones, especially storeys from the mainstream media. Participants in collaborative journalism usually see themselves as complementing and supplementing the regular media and, in some cases, holding mainstream media up for scrutiny. Unlike regular journalism with its publishing deadlines and the determination to deliver "complete" stories, collaborative journalists using blogs can develop or examine a storey one piece at a time, often updating a developing storey each day. The participating citizens can also debate, question, and further develop their own findings in an ongoing way.
