The Motion Picture Association of America (MPAA) and National Association of Theatre Owners (NATO) are tweaking the movie ratings system, according to The Hollywood Reporter. The decision marks the fulfillment of a promise made to Vice President Joe Biden in the wake of the school massacre in Newtown, Conneticut.

When the Obama administration outlined a series of proposals and executive actions to stop gun violence, the MPAA was part of a group from Hollywood that issued a statement in support of President Barack Obama’s ultimate goal.

In January, the MPAA and other members of the Hollywood group met with Vice President Joe Biden to discuss whether TV shows and movies promote gun violence. The White House Task Force on Gun Violence and representatives from the entertainment industry agreed to adjust the movie ratings system.

According to THR, the MPAA will deploy a new “Check the Box” campaign to explain to viewers why a movie was given a certain rating. In addition, the movie rating system will feature a new tag given to trailers acknowledging that the trailer is okay to play with the movie audiences came to see. The campaign will also feature a public service announcement and a new poster for theaters across America.

Speaking at CinemaCon, NATO president and chief executive John Fithian argued that Hollywood is making too many R-rated movies. In fact, he said that attendance has been down in 2013 because of the number of R-rated movies. He called on the industry to produce more family-friendly films, noting that Americans have chosen G/PG-rated films by their attendance numbers.

Do you think that the MPAA needs to change the movie ratings system? Should Hollywood produce fewer R-rated films? Share your thoughts in the comments section.
