Nigerian censors typically target certain kinds of idea, such as ethnic discussion, political opposition, and morality incorrectness.
An example of this kind of ethnic tension happened in 1957, when the Igbo newspaper the West African Pilot provided news with a clear bias against a Yoruba political group called Egbe Omo Oduduwa.
The Yorubas responded by launching their own news outlet called the Daily Service in order to retaliate and making corrections to those statements.
For example, the Tribune tend to be more considerate when mentioning issues related to the Yorubas while the Kaduna-based New Nigerians carefully vetted the northern opinion on national matters.
[2] Reporters without Borders cited killings, detentions and the brutalisation of journalists alongside targeted attempts to shrink the civic space by the Nigerian government as reason for the ranking.
On one occasion, a student named Oherei was arrested and accused of being a communist sympathizer when he published a novel called “Behind the Iron Curtain”.
[14] In 1978, the government created the News Agency of Nigeria (NAN), which was responsible for censoring electronic media, such as radio, television, and DVD.
[15] In June 1994, the National Film and Video Censors Board replaced the NAN as the official schedule agency of the government.
