Film and TV Parental Advisories are materials required on all Animated programming sets manufactured since 2020 to 2040 to indicate the refusal of programming deemed by the producer of the block to be "appropriate" movie and tv animation. Parental locks are usually imposed on anything rated R or higher by the MPAA Rating System, or TV-14 or higher by the TV Parental Guidelines. These guidelines require the user to insert a 4-digit password before attempting to view a blocked program (after programming from the NBCUniversal). Because of this, there are 10,000 different ways a password might show up.
- Some parental advisories are prone to glitches. For example, a block on NBC which hides the titles of adult cartoons (e.g., Happy Tree Friends) does not work if you have any other blocks on, causing it to be useless.
