Reporters Without Borders - Internet Annual report 2006 : Everyone's interested in the Internet - especially dictators

The Internet has revolutionised the world's media. Personal websites, blogs and discussion groups have given a voice to men and women who were once only passive consumers of information. It has made many newspaper readers and TV viewers into fairly successful amateur journalists. Dictators would seem powerless faced with this explosion of online material. How could they monitor the e-mails of China's 130 million users or censor the messages posted by Iran's 70,000 bloggers? The enemies of the Internet have unfortunately shown their determination and skill in doing just that. China was the first repressive country to realise that the Internet was an extraordinary tool of free expression and quickly assembled the money and personnel to spy on e-mail and censor "subversive" websites. The regime soon showed that the Internet, like traditional media, could be controlled. All that was needed was the right technology and to crack down on the first "cyber-dissidents.

OpenNet Initiative - "The Internet and Elections: the 2006 Presidential Election in Belarus."

The report presents the findings of ONI's effort to monitor the Internet during Belarus' recent presidential elections. Amidst fears that the authoritarian regime of President Aleksandr Lukashenka was going to close down Belarus political cyberspace during the elections, ONI testing found little evidence of systematic and comprehensive filtering, despite earlier ONI investigations that established the regimes capability to do so. ONI monitoring during the elections showed that, on average, opposition and independent media websites remained accessible throughout the monitoring period. ONI testing revealed a number of serious irregularities that disrupted access to certain opposition and independent media websites at strategic moments during and after the vote.
