Censorship plays a significant role in journalism in the Arab world. Censorship comes in a variety of forms: Self-censorship, Government Censorship (governments struggle to control through technological advances in ex. the internet), Ideology/Religious Censorship, and Tribal/Family/Alliances Censorship. Because Journalism in the Arab world comes with a range of dangers – journalists throughout the Arab world can be imprisoned, tortured, and even killed in their line of work – self-censorship is extremely important for many Arab journalists. A study conducted by the Center for Defending Freedom of Journalists (CDFJ) in Jordan, for example, found that the majority of Jordanian journalists exercise self-censorship. CPJ found that 34 journalists were killed in the region in 2012, 72 were imprisoned on December 1, 2012, and 126 were in exile from 2007 to 2012.
