TV Week's Josef Adalian reports that CBS and ABC Studios are still negotiating the licensing fees for Ghost Whisperer and any number of ideas are thrown into the speculative mix.
The article notes that ABC would be the most likely to pick it up in the event that CBS didn't, but I don't see it. The show works at 8pm on Fridays, but I think ABC Broadcasting likes its lot of unscripted programming on Friday nights and I would be very surprised if it didn't continue next year. ABC Broadcasting probably would balk at the licensing fees for the program even more than CBS!
The most likely scenario seems like this is just negotiating, and that CBS will pick the show up. Adalian reports NBC would be the least likely to pick it up, but also offered up this (Rampant speculation alert!)
NBC has already indicated that it's unlikely to make a serious play for "Ghost." Some executives at Fox are intrigued by the idea of buying "Ghost" -- and possibly pairing it with a second season of Joss Whedon's "Dollhouse" -- but it seems unlikely a deal would be done.
It's unlikely that ABC would pick it up. But the above scenario? That seems way beyond unlikely. In that context it's like saying "but it seems unlikely that I would grow a foot overnight and be signed by an NBA franchise."
So yes, it does seem....unlikely.
