Unique Facts About the First Movie Ratings
When movies started appearing in theaters over a century ago, nobody worried much about who watched what. Kids sat next to adults watching the same films, and parents didn’t think twice about it.
But as movies became more daring and pushed boundaries, people started asking important questions about what children should see on the big screen. The journey to creating movie ratings wasn’t smooth or simple.
Let’s look at some surprising facts about how this system came to be.
The Hays Code controlled Hollywood for decades

Before official ratings existed, Hollywood followed something called the Motion Picture Production Code, which everyone knew as the Hays Code. Will H. Hays, a former postmaster general, created strict rules in 1930 that told filmmakers exactly what they couldn’t show.
Married couples had to sleep in separate beds on screen. Criminals couldn’t win at the end of movies.
Even the word ‘pregnant’ was forbidden. This system didn’t rate movies for different audiences but instead tried to make every film acceptable for everyone by banning anything remotely controversial.
Jack Valenti created the rating system after just three months on the job

Jack Valenti took over as president of the Motion Picture Association of America in May 1966, and by November of that same year, he was already working on a new rating system. The old Hays Code was falling apart because directors like Alfred Hitchcock and Billy Wilder kept pushing against its outdated rules.
Valenti realized that censoring adult content completely wasn’t the answer. Instead, he thought parents should decide what their kids could watch, which led him to develop age-based categories.
The first rating system only had four categories

When the system launched on November 1, 1968, it was incredibly simple compared to today’s standards. Movies got labeled as G for general audiences, M for mature audiences (but all ages admitted), R for restricted (kids under 16 needed parents), or X for adults only.
The M rating caused immediate confusion because parents thought it meant something worse than it did. People kept mixing up which rating was more serious, and theaters struggled to explain the difference between M and R to frustrated customers.
They changed the M rating to GP after just two years

The confusion around M ratings got so bad that the MPAA replaced it with GP in 1970, which stood for General audiences, Parental guidance suggested. This didn’t really solve the problem though.
Parents still got confused, and the acronym didn’t clearly communicate what it meant. The rating stuck around for only two more years before they tried again with something different.
PG became the new middle ground in 1972

The MPAA dropped the GP label and switched to PG, which stood for Parental Guidance. This name finally made sense to regular people.
Parents understood immediately that these movies might have content they should know about before letting their kids watch. The change seems small, but it made a huge difference in how families approached movie choices at the theater.
Indiana Jones and the Temple of Doom created a rating gap

Steven Spielberg’s 1984 adventure film shocked parents who expected another fun romp like Raiders of the Lost Ark. The movie showed a beating heart getting ripped from someone’s chest, along with other intense scenes that felt too much for a PG movie.
But it wasn’t quite strong enough for an R rating either. Parents complained loudly, and Spielberg himself admitted the movie might have gone too far for younger viewers.
PG-13 was invented because of parental complaints

After the Temple of Doom controversy, along with similar issues with Gremlins, Spielberg suggested creating a rating between PG and R. The MPAA listened and introduced PG-13 on July 1, 1984.
Red Dawn became the first movie to receive this new rating when it hit theaters in August 1984. The addition gave parents much better information about what their kids would see.
The X rating wasn’t trademarked

Unlike the other ratings, the MPAA never trademarked X, which turned out to be a massive mistake. Adult film producers started slapping X ratings on their movies voluntarily, sometimes even using XX or XXX to advertise their content.
This association completely ruined the rating for legitimate filmmakers. Serious directors avoided X ratings like poison because nobody wanted their artistic work lumped together with adult entertainment.
NC-17 replaced X in 1990

The MPAA created NC-17 (No Children Under 17) to separate serious adult dramas from adult entertainment. Henry & June became the first film with this rating.
The MPAA trademarked NC-17 immediately to prevent the same problem that happened with X. Despite these precautions, the rating still carries a stigma, and many theaters refuse to show NC-17 films because they worry about their reputation.
Rating decisions happen behind closed doors

A secret board of parents working in Los Angeles watches every film and votes on its rating. The MPAA keeps their identities hidden to prevent filmmakers from lobbying or pressuring them.
These anonymous parents come from different backgrounds, but they all have children between five and seventeen years old. Critics argue this secrecy makes the process unfair, but the MPAA insists it protects the integrity of the ratings.
Studios can appeal ratings they don’t like

Filmmakers who disagree with their rating can present their case to an appeals board made up of industry professionals and theater owners. This board watches the film again and listens to arguments from both sides before voting.
The process costs money and doesn’t always work, but studios sometimes win these appeals. One or two cuts might bump an R down to PG-13, which can mean millions more in ticket sales.
The reason for a rating matters more than the rating itself

Since 1990, every rating comes with a brief explanation of why it received that classification. These descriptions tell parents about specific content like violence, language, or frightening scenes.
A PG-13 rating with ‘intense sequences of action violence’ means something different than one with ‘some suggestive material.’ These explanations help parents make informed choices based on what bothers them most.
Different countries have completely different systems

American ratings don’t transfer to other countries at all. Britain uses U, PG, 12A, 12, 15, and 18 ratings with different standards.
Japan rarely restricts films and trusts families to decide for themselves. France bases some ratings on whether content could harm young people psychologically.
A movie rated PG-13 in America might get stricter or looser ratings elsewhere depending on cultural attitudes toward violence, language, and other content.
Ratings affect a movie’s potential earnings dramatically

Studios fight hard for PG-13 ratings instead of R because the difference affects how much money a film can make. Teenagers represent a huge portion of moviegoers, and an R rating cuts off everyone under 17 without a parent.
Blockbuster action films almost always aim for PG-13 because losing the teen audience can cost tens of millions of dollars. Some directors shoot alternate versions of scenes so they can edit the movie down if needed.
Language gets treated differently than violence

American ratings tend to allow more violence in lower categories while being stricter about language and other content. A single use of a specific curse word automatically bumps a movie from PG-13 to R, but extended fight scenes with punching and kicking often stay at PG-13.
Streaming services created their own rating systems

Netflix, Hulu, and other platforms had to develop rating systems for their original content since the MPAA only rates theatrical releases. They generally follow similar guidelines but handle it internally.
The rating system constantly evolves with society

What shocked audiences in 1968 barely registers today, and the rating board adjusts its standards accordingly. Attitudes toward violence, language, and other content shift over time.
How ratings shaped modern filmmaking

Movie ratings changed how directors make films and how studios market them. Filmmakers now think about target audiences from the first day of writing scripts.
The system gave parents a tool to guide their families while letting artists create content for adults without censoring everything for children.
