A self-governing body with a censorship code, most visible (and most likely to receive mention) when that code is so draconian and unreasonable in its restrictions that it cripples an entire artistic medium. It usually comes about due to the pleas of the Moral Guardians and Media Watchdogs, but sometimes, it will come about due to some other circumstances (e.g. the beliefs of a specific corporation); regardless, the presence of such a Censorship Bureau will be a bane to the medium and usually result in it not being taken seriously. See also Animation Age Ghetto for a similar phenomenon.
