The technology is also heavily used today to get information from citizen journalists to the mainstream media. For example, during last year's wildfires in the USA, major news outlets like NBC and CNN's each received around 2,000 submissions of photos and video from people who sent in submissions via their mobile phones. The spread of information also intoxicated other social media sites like flickr, YouTube, and Twitter.
If you want to get involved with mobile activism, there is MobileActive.org, a site that is an all-volunteer community of people and organizations using mobile phones for social change. Their aim is to promote the use of mobile technology, which can help NGO's better serve their communities.
