TV events (miniseries and such, not so much regular shows)|
Oh yeah, if we're talking other than miniseries, huge agreement on the final episode of M*A*S*H. Also, the episode where Col. Blake died was one of those top 10 life-affecting fictional TV experiences for me.
Years ago, TV Guide put out a "100 biggest TV moments" (paraphrasing from memory) list, which I thought was a cool idea. It may actually have been two lists a few months apart, one fiction and one non but I'm not sure about that, but it was an interesting idea.
Of course, things like 9/11 and the Moon landing and the Challenger explosion and, for people a bit older than me, the Kennedy assassination would be huge on the nonfiction side (there were some sports upsets, etc. too there, but I don't follow any sport enough to really be caught up in those myself).
One on a much happier mood for me was the final episode of the 2nd Bob Newhart show, where he was an innkeeper in Vermont. The final ~30 seconds was one of the best surprise endings in television, and I just remember my girlfriend at the time and me just howling with shock and laughter for the rest of the evening.
