I want to know the answer to the following question:
In what year did the Motion Picture Association of America introduce its rating system?
All the background I'm provided with is that "TCM's film content has remained mostly uncut and uncolorized (with films natively filmed or post-produced in the format being those only ones presented in color), depending upon the original content of movies, particularly movies released after the 1968 implementation of the Motion Picture Association of America's ratings system and the concurrent disestablishment of the Motion Picture Production Code.". Is that enough to answer the question?
