The document discusses media dependency during the 2003 SARS outbreak in China. It summarizes that: 1) When the Chinese government banned news about SARS in early 2003, people turned to alternative sources like the internet and SMS to get information about the disease. Over 40% of people got information from sources other than mainstream media. 2) As SMS reports were initially treated as rumors, people sought confirmation on the internet, where similar reports were spreading. This showed a shift from SMS to increased dependency on the internet for SARS information. 3) The theory of media system dependency was seen in practice, as individuals relied on media systems like the internet for health information when the traditional media was restricted.
