the show improved and later received a full season? I can't think of any show that only received 13 eps and then after that season the ratings were so good that it lead to a full season.

My point is why not just cancel the show now and be done with it?

Parks & Recreation was given 16 episodes and pushed to mid-season in Season 3 and was then picked up for a full season in Season 4, and another full season the following year.

Cougar Town was put in a similar situation this year and was just renewed for a fourth season, to air on TBS.

There are also several shows that were picked up for 13 episodes and eventually received a back nine, such as Happy Endings this year. It's not a de-facto cancellation at all.

So if the Office receive 13 eps does that mean the show will air in the fall or spring?

It's depends.

Parks and Recreation Season 3 Premiere only happened(was pushed back) Mid-Season(During Winter-Spring 10-11)because Amy Poehler was Pregnant.

Same thing with 30 Rock Sixth season, It's was only pushed to Mid Seoasn because Tina was Pregnant.

It could go either way. NBC is supposedly announcing their line-up tomorrow so we'll know for sure then.

NBC has ordered a bunch of 13-episode seasons this year...Community, 30 Rock, Up All Night, and possibly The Office and Whitney. I suspect some will run in the fall (with a possible option for the back 9 if they do well, save for 30 Rock and probably The Office if it's really for 13) and some will be held for mid-season.

I read that Up all Night got a full season like Parks and Recreation

There hasn't been any official confirmation but Christina Applegate seemed to think on Twitter that the order was for 13 episodes.

The only show that has gotten a confirmed full season is Parks & Rec.

King of the Hill's 11th season only had 12 episodes and then it was renewed for 2 more and 46 episodes

I don't understand what the point is of renewing second year shows for only 13 episodes as it will take longer for them to hit syndication.
