Accusation of "ratings creep"

Although there has always been concern about the content of films, the MPAA has been accused of a "ratings creep", whereby the films that fell into specific ratings categories in 2010 contained more objectionable material than those that appeared in the same categories two decades earlier. A study put forward by the Harvard School of Public Health in 2004 concluded that there had been a significant increase in the level of profanity, sex and violence in films released between 1992 and 2003. Kimberly Thompson, director of the study, stated: "The findings demonstrate that ratings creep has occurred over the last decade and that today's movies contain significantly more violence, sex, and profanity on average than movies of the same rating a decade ago."
