The doctor is out — and I mean it this time. Really. NBC has decided that this will indeed be the final season of Frasier. Peacock execs had been in talks with Paramount (the show's producer) about a 12th season of the Cheers spin-off, but such a deal would have proven too costly for the network. NBC President Jeff Zucker made the announcement to members of the Television Critics Association (like me!) at a previously scheduled farewell press conference on Monday.
