When was National Association of Actors created?

The National Association of Actors (NAA) was not created. It is not a real organization.

There is a prominent organization called the Screen Actors Guild-American Federation of Television and Radio Artists (SAG-AFTRA). It was formed in 2012 through a merger of the Screen Actors Guild (SAG) and the American Federation of Television and Radio Artists (AFTRA).

It's possible you were thinking of SAG-AFTRA or another actors' organization. Could you please clarify your question?
