It is very recent. It seems that too many people were sticking just any old ordinary moment of awesome into Crowning Moment of Awesome, so the tvtropes mods responded with nukes.
I figured it had to be something like this. I mean, you can only have
one Crowning Moment of Awesome. Like new Battlestar Galactica. When Galactica jumps to New Caprica during the break out, proving that--unlike most modern SciFi spaceships, battlestars can not fly. Now, one can debate if this was THE CMoA for the series, but if it's not, it's not. You can break it down by character, but you can still only have one per character.
Or Rebuild of Evangelion. Lots of truly awesome stuff, and plenty of characters to have their own CMoA. Focus on Shinji. Here's a guy who is anti-(as in "not at all")heroic that there's at least one whole youtube series devoted to making fun of him. He really is kinda pathetic. In all fairness, he's supposed to be the kid off the street, thrown into an impossible situation. He's just more realistic than that trope usually is. So, during Evangelion 2.0 when Shinji restarts his power depleted EVA by
sheer force of will, and proceeds to (rather casually) kick the shit out of the most powerful angel faced so far, then proceeds (Again, basically by will alone) to initiate 4th Impact... that's a CROWNING Moment of Awesome.
I'm going to stand behind that one as not something you can argue with.
But there's someone--maybe on this forum--who would argue. And that's why a CMoA page, with examples, on a wiki is just not possible.
