Why is control of the media important in a totalitarian state

It enables the state to censor information and spread propaganda, is the right answer.

Explanation:

The term Totalitarianism is used to refer to a form of government in which the autocrat outlaws opposition groups, put restrictions to the opposition from individuals against the state, and employs a remarkably high degree of authority over private and public life. The totalitarianism has been regarded as the most intense and comprehensive form of authoritarianism.

In such form of government, all the political powers are held by the autocrats which exercise all-encompassing advertisement campaigns advertised by state-controlled mass media. The control of media in the totalitarianism is crucial as it enables the state to censor information and spread propaganda.
