From the comments, I think that the general answer is: We all recognize it, because a lot of different places used a logo sorta like this in the 90s.
And we can't pin it down exactly, because a lot of different places used a logo sorta like this in the 90s.
And being the 90s, a lot of that was never on the internet in the first place.
It rings very strong bells for me, and I don't think the reason is one that (at the time of this comment) has already been posted... But I can't for the life of me remember what it was for.
The problem is that there are a million logos from the 90s that have the same stylized "separate head". I'm attempting to attach an image to show off some examples. While I absolutely feel like I recognize the logo you've posted, I think it could be an amalgamation of many of them.
