I finally got around to submitting my list today.
I just went through the EoTVGS, 2nd edition, and made a list of all the shows I thought deserved to be on the list, remembering afterward to think of shows that have come out since the book was published. Some of the last ones I picked were a bit dicey, and I picked one personal favorite that I only know from its radio incarnation, though I gather that the original TV incarnation was practically the same as the radio version.
Ranking the shows was the tough part, and I don't think I would ever be satisfied with any ranking I came up with, so I finally gave up and just started putting things in the list in some rough kind of order, not worrying too much about getting everything exactly "right." I tended to give preference to long-running shows. Also, because I am not a tape trader, a small number of the shows on my list I have never seen or have only seen in clip form, but I chose them by reputation. I didn't feel comfortable putting them too high on the list, so most of those shows ended up in the bottom 20.
I'll be interested to see the full list and how everything ended up being ranked, just to see how far off my rankings are (Matt says all but a few of my choices are in the top 50 right now) from everyone else's.
