New media has been growing fast and influencing people’s lives in ways few things have done before. In 2010, China’s new media industry witnessed explosive development. But with “new” comes uncertainties and challenges. The following are brief reviews on the development of China’s new media and outlooks on its future.
I. Micro-blogging (微博)   
Short and convenient, micro-blogs also experienced “a big bang” in China last year, with the number of micro-bloggers at China’s popular portal(门户网站) sina.com.cn almost doubling in less than six months. Afterwards, the other three major web portals, including sohu.com, qq.com and 163.com, each set up their own micro-blogging services. With more government officials and entities(实体) registering, China’s micro-blogging services are expected to play a more important role in connecting the public and the governments in 2011.
