i've always heard that after the general societal unrest in the 1960's the leaders of the United States (business and political) Did whatever they could to shape society in order to prevent such tumult from happening again, to create a complacent populace. What specifically was done to do this?

I've heard/read both Zinn and Chomsky mention this but would like more specific info. I'd also love any reading material on this subject, sorry if this doesn't quite fit this subreddits purview. FYI i'm specifically seeking answers regarding about actions taken in the 70's, 80's, and 90's.

Thanks so much!
