I want to know What were Oreo cookies originally called?
It’s always been called Oreo but was a rip-off of the preexisting Hydrox.
Reported for forum change.
I’ll move this to GQ since it fits there better.
According to Wikipedia - 1912 Oreo Biscuit / 1921 Oreo Sandwich / 1948 Oreo Creme Sandwich / 1974 Oreo Chocolate Sandwich Cookie. Wikipedia can be a wonderful source of information, you should look into it.
What I found interesting in that article was that that the reasoning behind naming the cookie Oreo is unknown.
It’s round on both sides with a center of cream?
Yeah I know it’s not cream.
I was wondering, too, whether the OP was thinking of Hydrox, which still are being made, although I personally have never seen one in my life. I assume they must be very regional. ETA: Actually, no they don’t seem to be in production anymore. Looks like they ceased production in the late 90s, but had a limited release in the late 2000s.
They weren’t regional, but they weren’t as popular, so a lot of stores didn’t carry them.
There used to be a hydrox factory in the next town over from where I grew up, but I never knew anyone who ate them. The name – HYDROX – sounded like it was some sort of highly toxic chemical product (which, coincidentally, they also made in the next town over from where I grew up).
It was round on the faces and (c)re(amy) in the middle? 
I do recall seeing Hydrox in a store once. I thought, “Gee, Oreo knock-off cookies.” :smack:
Harlan Ellison has [del]ranted[/del] written about the superiority of Hydrox over Oreos. I hope this Google Books link works.
I remember having them when I was a kid. As I recall, they weren’t as good as Oreos.
I ate a LOT of Hydrox cookies in my time. Are we sure they no longer exist? internet search commences
Well, that didn’t take long:
Here’s the thing that makes Oreo the best: The cookies absorb milk SO WELL Dunk 'em for only 15-30 seconds and you got malleable gold in your hands good sir or madam!
I’ve tried DOZENS of other oreo-esque cookies and nothing comes close.
Including Hydrox (RIP).
So does dihydrogen monoxide. 
I always herd that oreo is the greek word for a hill, which the original cookie looked like because of a bump in the center.
I preferred Hydrox. Very different taste than Oreo. As a kid in Chicago in the 60s, they were only slightly less visible than Oreos in stores, on TV, etc.
I too grew up with Hydrox. Oreos were a treat, otherwise we got (what we thought) were the generic version. Wasn’t until recently (thanks Internet!) that I learned the truth.
Funny thing, truth. Makes me appreciate them more, but doesn’t make me think they tasted any better–yet an item’s provenance is an intrinsic part of the psychological experience of taste.
I always associated the name ‘Oreo’ with the chant from the Winkies of Oz. Not that I thought it was a direct translation, but Oreos are so good they must come from that technicolor wonderland.
I preferred Hydrox, too, but I always think of them as Hydrox Sunshine for some reason. I grew up in the Chicago area, too.
Like the famous *Oreopagus * – The “Cookie of Ares” – on the Athenian Acropolis?
