user group among all online-payment providers. Online gaming As of 2009, China is the largest market for online games. The country has 368 million internet users playing online games and the industry was worth US$13.5 billion in 2013. 73% of gamers are male, 27% are female. In 2007, the Ministry of Culture (MoC) and General Administration of Press and Publication (GAPP) along with several other agencies implemented the Online Game Anti-Addiction System which aimed to stop video game addiction in youth.

Many dating and "adult chat" sites, both Chinese and foreign, have been blocked. Some, however, continue to be accessible, although this appears to be due more to the Chinese government's ignorance of their existence than any particular policy of leniency. Censorship The Golden Shield Project was proposed to the State Council by Premier Zhu Rongji in 1993. As a massive surveillance and content control system, it was launched in November 2000, and became known as the Great Firewall of China.
