of Le Monde have been censored since 2006 according to RSF. Libération was censored in February 2007 following the publication of an article by Taoufik Ben Brik; it was the first time since 1992 that Tunis had censored it. Television The state exercises a monopoly on domestic television transmissions, although satellite dishes are popular and offer access to foreign broadcasts. Radio There is a small number of private radio stations, but they do not independently report news. A permit is required to establish a radio station. Electoral endorsements of candidates are not permitted in the private media. Internet Internet censorship in Tunisia significantly decreased in January 2011, following the ouster of President Zine El Abidine Ben Ali, as the new acting government: proclaimed complete freedom of information and expression as a fundamental principle, abolished the information ministry, and removed filters on social networking sites such as Facebook and YouTube. Some Internet censorship reemerged when in May 2011: the Permanent Military Tribunal of Tunis ordered four Facebook pages blocked for attempting "to damage the reputation of the military institution and, its leaders, by the publishing of video clips and, the circulation of comments and, articles that aim to destabilize the trust of citizens in the national army, and spread disorder and chaos in the country", and a court ordered the Tunisian Internet Agency (ATI) to block porn sites on the grounds that they posed a threat to minors and Muslim values. In 2012 the OpenNet Initiative found no evidence of Internet filtering in the political, social, conflict/security, and Internet tools areas. Tunisia is listed as "Under Surveillance" by Reporters Without Borders in 2011. Prior to January 2011 the Ben Ali regime had blocked thousands of websites (such as pornography, mail, search engine cached pages, online documents conversion and translation services) and peer-to-peer and FTP transfer using a transparent proxy and port blocking. Cyber dissidents including pro-democracy lawyer Mohammed Abbou were jailed by the Tunisian government for their online activities. Post-Ben Ali Following the resignation of President Ben Ali in the 2011 Tunisian Revolution, press reports indicated that books banned under the previous regime, including La régente de Carthage and L'assassinat de Salah Ben Youssef, had appeared in bookstores and were openly circulating. In 2012, Tunisian activists and human rights groups expressed concerns following several high-profile cases that the nation's Islamist leadership was cracking down on freedom of expression.
