Internet filtering in Pakistan is regulated by the Pakistan Telecommunications Authority (PTA) and the Federal Investigation Agency (FIA) under the direction of the government, the Supreme Court of Pakistan, and the Ministry of Information Technology (MoIT). Although the majority of filtering in Pakistan is intermittent—such as the occasional block on a major Web site like Blogspot or YouTube—the PTA continues to block sites containing content it considers to be blasphemous, anti-Islamic, or threatening to internal security. Online civil society activism that began in order to protect free expression in the country continues to expand as citizens utilize new media to disseminate information and organize.
