You should know that information control, it's one of the fundamental weapons and control powers a government administration has. Every government knows this, and every government uses it (even though some use it less than others).
That's something you should think about. At least the Chinese government stated it publicly, while others mask it as democracy freedom.
I talk about governments and politics, but you should count religion in it. Do you think the Catholic Church (eg. the Vatican) doesn't influence decisions of governments? (I know something about this)
It's important to note that christian descendant and "allies" control the majority of media. Eg. in Albania there is an estimation of 80/20% of Muslims (majority non practitioners)/Christians, while the government administration 80/20% Christians/Muslims.
EDIT: I was talking about worldwide majority, not national or regional.
