From another thread:
Emphasis mine
So, I was very, very wrong. I was sure they would have created something new with appeal directed at GenZ players. Not the first time I have been wrong. Oh well.
But, I am curious why. Why Greyhawk? I mean, sure, 50th anniversary, but is that all? What does Greyhawk have about it that makes it a good fit for the vast majority of current and potential future players who have never known GH?
For the record, I am a GenXer who grew up with BECMI and 2E. I never played in Greyhawk, but I was aware of it because of Dragon Magazine mostly. Until Eberron appeared with 3.5, the only setting I used with an depth or regularity was Krynn/Dragonlance. We played in "The Known World" but never got more in depth than what was in the Expert book.
Anyway: why do YOU think they decided on Greyhawk for the example DMG setting?
