Sci Fi Wire has more proof (as if it's necessary) that Jeff Zucker is deeply stupid:

NBC let the Dec. 11 deadline pass for it to pick up additional episodes of its low-rated time-travel series Journeyman, in effect canceling the series, according to The Hollywood Reporter.

Journeyman is one of the smartest shows I've seen in years. It handles time travel in a far smarter way than just about any show I've ever seen. I suppose it doesn't have enough sex appeal for the rather limited minds of the staff at NBC - they'll come up with some lame sitcom or reality show instead.

I'd bet that the audience that watches Journeyman probably has more disposable income than the one that watches whatever they put in its place - sadly, Zucker and his merry band of morons are too stupid to figure that out.
