Question on All-Time Great Wrestling Promos

Greetings, El Jefe, Oh Wise and Majestic One. Detective Munch from the Blog.

Had a question on all-time great promos from different promotions/territories/eras. Obviously there are certain examples that most fans agree are all-time great promos – Dusty Rhodes and his “Hard Times” interview, Jake Roberts at WrestleMania VI, etc. My question for you is, how long does it take for a promo to go from “that was really good” to “that was an all-time great”?

Would people watching WrestleMania III know that Randy Savage's promo was an all-timer when they were watching, or did it only become apparent months/years after the fact? I'm curious if there's a time window on when fans recognize that what they've seen is truly epic, or if there's just that “It” factor that resonates with fans immediately when a classic promo is delivered?

I don't think there's any set amount of time.  Hell, I didn't even know about Randy Savage's “cream of the crop” promo until many years afterwards, long after it had become a meme.
