Yes, it's that time of year… The time for the dreaded Endangered TV Series list. Right now, TV networks are working on pilots for potential new series for next season. And that means eventually, something's gotta go. In the next few weeks, many big decisions will be made on what to get rid of and what to save. Yes, there are some shows that clearly are getting renewed, even if a formal announcement has yet to be made. But there are also many shows that are still in that uncertain place, some more dangerously than others.

Keep checking back to this story in the weeks to come, as we'll no doubt be updating frequently, as some shows get the good news that they're renewed, while others find their time on our televisions have some to an end.

Also, let me note we're keeping this list strictly for network series, not cable, who don't operate on the more formal September to May TV season and the final decisions on what to renew or cancel that come about by the network Upfronts in May.

Update (3/26) to Terra Nova added on the Won't Be Back page.

After a strong debut, ratings continued to drop for the series, sometimes dipping below Terra Nova's level. On the other hand, the numbers look to have now stabilized and it's likely not nearly as expensive as Terra Nova. Still, the future is very uncertain for the J.J. Abrams-produced series.

We love this show here at IGN, making us extra nervous about how it would do. But for now, there's reason for cautious optimism. As we'll mention many times on this page, the bar for success is pretty low on NBC these days. And Awake is at least doing okay by the network's standards on a tough night, and growing out of its lead-in.

NBC's attempt at a Wednesday night comedy block hasn't delivered, and Chelsea – lacking any real critical support or buzz – is unlikely to return.

Already facing an uphill battle, with NBC burning through all six episodes in three weeks, Bent has premiered to incredibly low ratings - as in, worse than The Paul Reiser Show ratings. All of which no doubt means the show won't be back, barring a surprising uptick in the two weeks it has left to make any impact.

FOX actually ordered a full 22 episodes for Season 2 of this show, with the intent of airing a portion of them next season, if they decide to keep it on the schedule. For now, it's looking likely, as Bob continues to do okay, albeit still the lowest rated show, among the Sunday night animation lineup.

Picked up for a second season after its midseason run last spring, Body of Proof has failed to find a larger audience this past year and struggled among ABC's lineup.

Miraculously resurrected after initially being cancelled last year, Breaking In has unfortunately returned to increasingly weak ratings, not holding on to much of its strong lead-in, New Girl. Contra Security has managed to buck the odds in the past, so we'll see what happens this time out.

Yep, it's stupid to live in a world where Community is in danger. But even on NBC, where ratings are bad down the line, Community has struggled, leading to it getting benched for awhile (new episodes resume March 15th). But don't give up! The fact that the Chelsea/Whitney combo is bombing even harder; the fact that NBC has so few shows to tout in any way; the fact that Community gets them such positive press; and the potential for Sony (who produce the series) to cut the network a good deal to get a fourth season -- and enough episodes for syndication -- all give us hope we'll see Greendale again next year.

Update: Community returned to surprisingly good ratings on March 15th. While nothing is set in stone, its chances are looking increasingly good to return. The show's creator, Dan Harmon, said he'd place the odds at 70/30 that they'll be back while speaking at WonderCon.

Like Community, which it's shared some good humored back and forth (and cameo exchanges) with, Cougar Town has critical support and a small but loving audience. But the show, held for midseason this year, continues to struggle in its new Tuesday timeslot and in an ominous (but not fatal) sign, a couple of the cast members have now signed onto new pilots, in "second position" – meaning they stick with Cougar Town if it is renewed. But it's hard to deny these are tough times for Jules and her friends...

The CSI franchise isn't what it once was, and it may be time for one or both of the spinoffs to say goodbye. While New York is more likely to be cut first, Miami is in danger as well.

See above.

This Bones spinoff disappointed in its early showings, not scoring nearly as high ratings as the show that spawned it. It's moving to Fridays in April, which is rarely a good sign, but let's see if it shows any signs of life there. After all, the next show on this list managed to get renewed last year, after being moved to Fridays...

Ah, a perennial part of our Endangered Series list! It's amazing this cool show has made it this far, but it's in a more dangerous position than ever, as FOX's president has noted that Fringe is now outright losing money for them. Still, could Warner Bros., who produce the series, offer FOX a good enough deal that they would bring Fringe back for one final season? After Warners and NBC made a similar (and rather surprising) deal on Chuck last year, we don't want to say it's impossible.

A recent addition to Sunday nights, ABC's soapy new Sunday night show needs to stabilize soon if the GCB will live on to see the fall. But for now, the show is in the "wait and see how it goes" area.

CBS's Friday night series about an arrogant doctor learning to be a better man (you know, with the help of his dead wife) has struggled on Fridays and is unlikely to be back.

No longer getting the buzz or the ratings it once did, Gossip Girl could be over if The CW truly decides to clean house this season. But with the cast under contract for one more year, it's also very possible CW will renew it, touting that it will be the final season.

Harry's Law gets awful ratings in the desired 18-49 demographic, but in actual viewers, it's among NBC's highest viewed shows. Does that matter? Almost never, especially when the viewers are as old as this show skews. But NBC is in such a bad place, who knows… They might actually want to keep anyone actually watching that they can.

The CW didn't have nearly the hoped-for splash with their two new star-driven series last fall, including this Rachel Bilson vehicle. Still, Hart of Dixie has held up better than some series on the network, and has a shot to come back.

It could go either way for the animated version of the hit movie, which at least boasted better ratings than Allen Gregory did in the fall. But would FOX bring back both Napoleon and Bob's Burgers or is it more likely one or the other?

It pains us to put this show on this list, because it's so damn good. But the fact is, Nikita is The CW's lowest-rated scripted series. But does the fact that it has a dedicated core audience and that it airs in a tough Friday timeslot help its case? We just don't know yet if the show, like its title character, will get the chance to keep on kicking ass.

- The CW

Who in their right mind wouldn't want this on their TV every week?

Word is, The CW wants to really shake things up and broaden their appeal. For a network that, in general, has much lower ratings than the others, and has particularly been floundering this past year, that means a lot of shows are suddenly in a precarious position. Such is the case with 90210.

ABC keeps insisting this series is in contention for next season. But with a shortened season and very weak ratings, it sounds pretty dubious…

The CW has never succeeded when it comes to launching non-Top Model reality hits. This one is another DOA series that is likely gone soon…

Sarah Michelle Gellar's much-hyped return to TV was a big non-starter for The CW last fall, not making nearly the hoped-for ratings impact – and lacking even the kind of critical response and strong core following that would at least give it some buzz. At this point, the network may just want to cut their losses…

Attempting to do bring horror movie vibes (and even found footage techniques) to TV, this Steven Spielberg and Oren Peli (Paranormal Activity) produced series debuted to surprisingly tepid ratings. Dropping in subsequent weeks, it's looking increasingly likely its eight episode run will be its only season.

Update: Right on the heels of the season finale airing, before ABC has made any public decision on the show, comes word that Netflix is considering picking up The River. While this doesn't bode well for its future on ABC, it does sound promising, given how early on these conversations are taking place with ABC Studios, who produce The River.

Rob has done okay for CBS on Thursday nights. But it's always hard to judge how well a show following the powerhouse of The Big Bang Theory needs to do for CBS to deem it worthy to bring back.

Perennial benchwarmer Rules of Engagement got sidelined again for Rob, yet whenever CBS airs it, it gets dependable ratings. So once again, the network may order another season – which, per usual, could air in the fall, the spring, or whenever they need to replace a cancelled series.

Too many obvious jokes to make about the title… Suffice to say, on a network with a lot of hit procedurals, Unforgettable has floundered and is almost certainly not coming back.

Oh, Whitney. A big punching bag in the fall, Whitney stood out among NBC's Thursday night lineup both for its multi-camera style and for how much weaker it was comedically. A move to Wednesday nights has only proven what most suspected: Without The Office as a lead-in, few care to watch Whitney.
