> "MPAA ratings for movies" (IANAL) That demonstrates the opposite: that's a voluntary system with no force of law behind it—the private sector "self-regulating" itself, if you will. The film rating systems were created under threat of legislation in the first half of the 20th century (so, in lieu of actual legislation). The transformative 1st Amendment rulings of the Warren Court would have made such laws unconstitutional after the 1960's, but the dynamic that created these codes predates that—predates the modern judicial interpretation of the 1st Amendment. https://en.wikipedia.org/wiki/Hays_Code https://en.wikipedia.org/wiki/Hays_Code (history background) https://en.wikipedia.org/wiki/Motion_Picture_Association_film_rating_system https://en.wikipedia.org/wiki/Motion_Picture_Association_fil...
