I think Paramount made money off the series. But I think the question is: how long has it been since it has drawn in any meaningful cash?
Stations weren't really falling all over each other to run it in strip syndication. I can't remember the last time it ran with any regularity here in the States. Honestly, I don't know what any of this means for a DS9 HD release. Depends on what CBS thinks it can make back in syndication/streaming sales...
