"You know what? They're wrong, and I'm going to wait that out," she says.

they are just going to have another revolving door of awful new comedies that get pulled rather quickly (hopefully).

I also posted this (http://www.imdb.com/title/tt0496424/board/flat/221184564?p=1) in the General Sitcoms Questions and Discussion (http://www.sitcomsonline.com/boards/showthread.php?t=323000) forum:
Lets start with 30 Rock (http://www.avclub.com/article/i30-rockis-improbable-survival-highlights-the-show-88857).

A great show with great writing and a great cast but was never a hit in the ratings (http://www.hollywoodreporter.com/news/fall-tv-why-are-comedies-401156). Even Tina Fey herself has said that the show only lasted as long (http://deadline.com/2013/01/30-rock-finale-tina-fey-how-it-changed-tv-417909/) as it did because it was an awards contender. This is where NBC made a mistake. From business (http://adage.com/article/media-watercooler/tina-fey-s-30-rock-hits-syndication-time/137849/) point of view, 30 Rock should've been cancelled after its second season when it was clear it was never going to be a true hit (http://screenrant.com/nbc-ratings-comedy-shows/) for NBC (http://www.theatlantic.com/entertainment/archive/2012/03/how-must-see-tv-lost-its-way/254511/). While Tina Fey's star power increased dramatically after her Sarah Palin skits on SNL in 2008, her star power did nothing to help her own show. If anything, the ratings got worse after that. To keep a show on the air just because it gets awards and to keep a certain star on their network is a bad business strategy in my opinion. Even now that 30 Rock is over, its ratings in syndication (http://deadline.com/2011/11/will-syndication-run-give-30-rock-much-needed-ratings-boost-on-nbc-195353/) are so-so at best.

Let's be very generous and say that 30 Rock could survive because it had a demographic that could draw Thursday night movie ad revenues. You still can't run a whole week's schedule on that sort of niche audience.

Shows like 30 Rock seemed to mostly appeal to a youngish, upscale demographic that would otherwise, seldomly watch television and advertisers would pay dearly to reach.

Those niche sitcoms killed any opportunity for NBC to gain any traction with comedies on Thursday, and NBC is still picking wrong comedies single and multi-cams (People are Talking).

NBCs' comedy reign on Thursday is dead.
