Internet: as a venue for state control and rebellion, more than 20 nations block and filter Internet content

[benton] The Internet is no longer just an essential channel for commerce, entertainment and information. It has also become a stage for state control — and rebellion against it. Computers are becoming more crucial in global conflicts, not only in spying and military action, but also in determining what information reaches people around the globe. More than 20 countries now use increasingly sophisticated blocking and filtering systems for Internet content, according to Reporters Without Borders, a Paris-based group that encourages freedom of the press. Although the most aggressive filtering systems have been erected by authoritarian governments like those in Iran, China, Pakistan, Saudi Arabia and Syria, some Western democracies are also beginning to filter some content, including child pornography and other sexually oriented material. In response, a disparate alliance of political and religious activists, civil libertarians, Internet entrepreneurs, diplomats and even military officers and intelligence agents are now challenging growing Internet censorship.
