National Board of Advisory Classification

The National Board of Advisory Classification (NBAC, formerly the National Board of Film Advisory) is an organization that reviews films and television series and assigns a classification determining the audience that the film or series is suitable for, serving Koria.

History
In 1928, the cinema at Neohog Theatre began marking films with potentially objectionable content by ending the film's name with an ! exclamation mark enclosed in a circle. Many other Korian cinemas began to follow this system.

A common complaint about this system was the lack of standard of what was considered objectionable, and in 1930, Teleport Pictures, a Korian cinema that used the exclamation mark system was attempted to be sued for showing a horror film without the exclamation mark and letting multiple children in to watch it. After this criticism, Neohog Theatre and smaller cinemas formed the National Board of Film Advisory (NBFA) to fix these criticisms.

The National Board of Film Advisory began operations in May 1931 and had two classifications: an exclamation mark in a triangle to clarify that the film may contain content inappropriate for children, and an exclamation mark in a circle to clarify that the film can only be viewed by people aged 16 years and over. A film without a classification clarified that the film should be suitable for everyone. The NBFA's classifications were required to be used by cinemas after the Film Advisory Act 1931.

In 1957, KCB introduced the watershed to Korian television, requiring an on-screen transparent exclamation mark in a triangle to be shown on inappropriate programs that can air from 8:00pm to 1:00am.

In 1960, the National Board of Film Advisory renamed to the National Board of Advisory Classification, and gave the classifications their first overhaul: The certificate of classification is now shown at the beginning of a film or television program, unless it is rated G. The watershed allows R programs to be aired on television.
 * G — General audiences
 * PG — Parental Guidance
 * R — Restricted to people 16 years and older
 * X — Restricted to people 18 years and older

In 1990, the NBAC gave the classifications their second overhaul and began calling them ratings, which is the current set.

In 1993, the NBAC began rating video games after the Congressional hearings on video games, until 2000 when the National Board of Game Advisory was formed.
