Jeff Zucker called it “a mistake.” Jeff Gaspin said it was probably “too soon.” So, it would seem now that universally, NBC's move to strip Jay Leno's show at 10 p.m. will be remembered right up there with New Coke and the XFL. Why exactly it tanked will be debated. I think a big part of it, from watching the show and actually sitting down with Leno one-on-one for an hour in his green room late last year, was that he just never wanted to do this at all.
