Wow, I never expected this to happen. But I heard a rumor that they had shafted Geneon USA, driving them out of business, and Japanese producers wouldn't do business with them after that.
Having ADV out of business is basically the only way that something like Bubblegum Crisis 2040 was going to get loose, because they actually paid for eps 25 & 26 to be made, so they permanently owned it rather than leased it from a Japanese company. Good news for Macross fans, too. Unfortunately, the titles they had rights to, have, in many cases, nearly disappeared from the Net, or are only to be found in really old formats, like .ogm .
It's too bad that ADV had the nasty habit of starting fights with everybody, because their dubbing was actually good, and they didn't censor stuff. And by everybody, I mean Geneon, this site, fansubbers, other torrent boards, etc.
