Early in 2006 Google launched a self-censoring Chinese search engine, google.cn. As with Microsoft and Yahoo, the Chinese version of Google (called “Gu Ge” in Chinese) affects Chinese users by restricting search results for topics such as “human rights”, “political reform”, “Tiananmen Square” and “Falun Gong”, among others. Google’s chief executive has defended Google's decision to cooperate with censors, claiming that accepting China’s restrictions was unavoidable.
