Citizen journalism

Citizen video reporting dates back as early as the development of camcorders, but all videos were screened by the local media outlets of the time, until its spread has been aided by free upload websites in which censorship is limited to make a vast amount of videos available to anyone who wants it. Scenes rarely broadcast on television, and many first-witnessed scenes have since become publicly available.
The tsunami caused by the December 26, 2004 earthquake strikes Ao Nang, Thailand.
Notably, in December 2004, tourist videos on the Indian Ocean earthquake and tsunami offered worldwide audiences the first scenes of the disaster. In December 2003, videos in Hong Kong showing the bully in De La Salle School has outraged the public, raised a wide concern on school violence and led to the arrest of 11 students.
