I research about the role of amateur videos by internet like information tools in situations without press freedom (demonstrations, terrorism, police or politicy violence, actions against civil people).
I find the use of YouTube as a news/informational source to be really interesting, so I suggest this article to you: http://www.sciencedirect.com/science/article/pii/S074937970900806X
I found a very interesting bibliography about this issue in Gillmor, D. (2006). We the media: Grassroots journalism by the people, for the people. " O'Reilly Media, Inc.". and Andén-Papadopoulos, K., & Pantti, M. (2013). Re-imagining crisis reporting: Professional ideology of journalists and citizen eyewitness images. Journalism, 1464884913479055.
Profesora, en mi libro: "Máquina de Quimeras: Raza y etnicidad en los juegos de video: racismo, odio y prejuicios", como parte de la investigación realizada que comencé en el 2012, tengo muchas fuentes que tal vez le interesen. Si quiere le envío una copia. Saludos.
