During the 60’s, the movie industry was growing tired of the Production Code and its limitations. Starting in the mid-30’s the Code dictated what could or could not be in a movie at all. Certain restrictions were relaxed over time, but others were pretty steadfast. In the early 70’s the Code was dropped in favor of the voluntary rating system we have today. So film makers could do what they wished, but risked commercial failure instead due to cinemas not accepting ratings of X (later turned to NC17, but with the same issues).
