Are you an Oreo person or a Hydrox person? I guess I should change that to "were" because the Hydrox cookie is no more.
Now, this might not be news to everyone, since it happened in 2003! But Kellogg's was so low-key about it that a lot of people simply didn't realize it (besides hardcore Hydrox fans, of course). The Wall Street Journal investigated and found out that it was discontinued five years ago after the company realized they couldn't compete with Oreos. The interesting thing is that several people still say they see them once in a while, in stores and on airplanes.
I have to admit that I'm an Oreo person, and I think the reason why I never bought Hydrox was because I just thought they were a knockoff and tasted like Oreos. Now I wish they'd come back so I can try them again. Supposedly the cream in the middle was less sweet?
