One would hope that even at their most insane, GSN would seriously not consider moving the call-in-and-lose shows to prime time. What they might do is bring in elements of those shows as interstitials to what they already have, perhaps in some cases replacing advertising in a break.
The best example? What NBC is doing with their prime time games and with "The Apprentice" (Lucky Case, You vs. 100, Get Rich with Trump). And the home viewer game on "Identity" is packaged as a product placement deal.
No, I don't think people would accept "PlayMania" in prime time on GSN. I wouldn't accept a 24/7 call-in-and-lose channel, but we all know that those things exist in Europe and if there's a perception that they'll make money over here, they will come here soon enough.
