Ideas for Media Social History Paper?

Question From User - Answers in Comments.

The goal of the paper is to conduct original research on some aspect of media and social history. I need to pick either medium: newspaper or magazine. Then pick a time period to study, up until 1975. Then I need to pick an American location for study, unless I am looking at a national publication.

Anyone have any great ideas?

I've thought about the bombing of Hiroshima and Nagasaki and media coverage of Roe vs. Wade. But definitely feel like I want more to choose from.

Thanks!
