What was the last great unifying cultural event?
The M*A*S*H* finally was certainly huge; we had just gotten a VCR, and I think that might've been one of the first things my dad recorded with it. I was one of the 77%, of course, but was too young to really understand the gravity of a communal event like that.
For me, the 1st one that comes to mind is Seinfeld's finale. A distant second might be the live footage of Columbine. obviously 2 VERY different events, but as a nation, we watched both together.
P.S. Our desks look similar! Mine is littered with notes I scribble on old teletype messages from work, but it's nice to see another analog native at work. :)
If you mean TV, then maybe "Who Shot J.R." was big--not as intense as M.A.S.H. of course. I think the Harry Potter books, then movies were huge. A lot of books and movies in a short period. https://en.wikipedia.org/wiki/List_of_best-selling_books#List_of_best-selling_book_series
