The post-lunch session at Mobile Media 2007 is started by Janey Gordon, who focusses on the use of mobile phones in critical situations, contributing to the public sphere; she's focussing especially on the SARS outbreak in China in 2003, the tsunami in the Indian ocean in 2004, and the London bombings in 2005. SARS was initially underreported, and news about it was restricted by the Chinese government, until a Beijing doctor became a whistleblower about the crisis; in this context, the mobile phone became a key tool for the spread of grassroots information about it. SMS messages were later also used to send out blanket information to the public in order to manage public knowledge.
