Google owns the most extensive archives of usenet because it has put in the effort. There's no reason that anyone else couldn't have done the same, they just failed to do so. Google acquired dejanews, an old usenet archival site, and they sought out personal archives as well to expand the collection. We should be happy that they have done anything, the more likely outcome was for no comprehensive archive ever to have been made.
No, it's because they bought the company, Deja, that was responsible for putting the first widespread web interface on Usenet. Google groups used to be just Usenet until it forked into something different (user lists). http://en.wikipedia.org/wiki/Google_Groups#Deja_News
Did you read my post all the way through? I know they acquired dejanews, I said it. But they also went to the effort to make use of deja's archive and to keep it safe. More so, they sought out private usenet archives and integrated them into their collection. Indeed, the very message that sparked this discussion comes from the work that google did and not from the dejanews archive since it dates to 1991, 4 years before deja began operations.

I think that's not the case, I think the existence of Google Groups is regarded as "good enough" by groups that might otherwise be doing archiving (Internet Archive, for one). That Groups started out with good intentions isn't surprising, but it has evolved into something completely different. If the intent was to archive an important part of the history of the internet, viewing posts wouldn't be behind a login-wall.
It isn't behind a login wall. If you saw a login screen when trying to access the link, then you must be partially logged into Google in the first place. Try the link in an incognito window and you'll see that no login is required.
Yah I thought I did. I didn't see Deja the first time I read it. May be my mistake because I'm tired from hacking all night (5am here), but it seemed shorter (the whole middle sentence wasn't there) the first time I read your comment.
