Wikipedia: Citizen journalism, also known as public or participatory journalism, is the act of citizens "playing an active role in the process of collecting, reporting, analyzing and disseminating news and information," according to the seminal report We Media: How Audiences are Shaping the Future of News and Information, by Shayne Bowman and Chris Willis. They say, "The intent of this participation is to provide independent, reliable, accurate, wide-ranging and relevant information that a democracy requires." Citizen journalism should not be confused with civic journalism, which is practiced by professional journalists. Citizen journalism is a specific form of citizen media as well as user generated content.
In a 2003 Online Journalism Review article, J. D. Lasica classifies media for citizen journalism into the following types: 1) Audience participation (such as user comments attached to news stories, personal blogs, photos or video footage captured from personal mobile cameras, or local news written by residents of a community), 2) Independent news and information Websites (Consumer Reports, the Drudge Report), 3) Full-fledged participatory news sites (OhmyNews), 4) Collaborative and contributory media sites (Slashdot, Kuro5hin), 5) Other kinds of "thin media." (mailing lists, email newsletters), and 6) Personal broadcasting sites (video broadcast sites such as (KenRadio).
Dan Gillmor, former technology columnist with the San Jose Mercury News, is one of the foremost proponents of citizen journalism, and founded a nonprofit, the Center for Citizen Media, to help promote it. The Canadian Broadcasting Corporation's French-language television network has also organized a weekly public affairs program called, "5 sur 5", which has been organizing and promoting citizen-based journalism since 2001. On the program, viewers submit questions on a wide variety of topics, and they, accompanied by staff journalists, get to interview experts to obtain answers to their questions.
