Internet censorship is censorship except only over the internet. This may include websites censoring information, or entire websites being censored. Google is known for changing its search results to censor information.

As more people in more places begin using the Internet for important activities, there is an increase in online censorship, using increasingly sophisticated techniques. The motives, scope, and effectiveness of Internet censorship vary widely from country to country. The countries engaged in state-mandated filtering are clustered in three main regions of the world: east Asia, central Asia, and the MENA: Middle East & North Africa.
