Times change

In the late 20's, movie audiences were getting tired of hearing about the decadent lifestyles of the Hollywood elite. The public was also getting tired of "wild" movies featuring flappers, smoking, drinking, and gangsters.
In 1930, the movie industry decided to regulate itself. They instituted a moral "code" which was completely voluntary. As expected, very few studios followed this code.
Some of the rules included....

1) no swearing
2) no vulgar terms
3) no revealing undergarments
4) don't show the intimacies of married life
5) don't use questionable words (pregnant, hot, tomcat, virgin)
6) the good guys must win in the end
7) no screen kiss can last longer than 7 feet of film

For the most part, these rules remained in effect for the next 35 years, until the movie rating system (G, PG, R, X) replaced them in the late 60's.

Commentary by Hokie Bob:
1 & 2. Acceptable language in the movies and TV now includes terms that would not have even been heard in private conversations.
3. Nudity, hence no garments, has become acceptable.
4. Intimacies by unmarried couples of any combination of sexes is OK.
5. Who's the good guy is in the eyes of the beholder.
6. The length of the kiss has actually been decreased or eliminated entirely, thus allowing for more time for what follows.

And finally - the violence. The graphic and gory scenes of today's "entertainment" never existed back then. But hey, smoking in the movies and TV has been cut down!

Yes, times change as do our standards.
