To no surprise, NBC has announced that they’re renewing three popular comedies for the 2011-12 season. The Office will be back (sans Steve Carell) for season eight. Parks and Recreation will return for season four and Community has been renewed for season three.

Airing on Thursday nights, The Office and Parks and Recreation are the highest-rated scripted shows on the network. Community is further down the list of NBC season averages and reasonably could have gone either way. NBC’s 30 Rock was renewed for season six last November. The two other NBC sitcoms, Perfect Couples and Outsourced, have not been renewed.

Perfect Couples has been performing terribly and certainly won’t be back for season two. Outsourced had a very strong start but essentially keeps falling each week. The last original installment registered just a 1.4 rating in the coveted 18-49 demographic, a loss of 61% from its September debut. It’s tough to imagine that Outsourced will be back next season.

Here’s the press release from NBC:

NBC PICKS UP THREE RETURNING COMEDIES FOR 2011-12 IN “THE OFFICE,” “PARKS AND RECREATION” AND “COMMUNITY”

UNIVERSAL CITY, Calif. – March 17, 2011 – NBC has issued pickups for three returning comedy series in 2011-12 that include “The Office,” “Parks and Recreation” and “Community,” it was announced today by Bob Greenblatt, Chairman, NBC Entertainment.

“I am so pleased to renew these three outstanding comedies which are all at the top of their game creatively,” said Greenblatt. “Along with ’30 Rock,’ they represent the best of what the NBC comedy brand stands for in terms of originality, wit, and sophistication. ‘The Office’ continues to fire on all cylinders on the most competitive night of television; ‘Parks and Recreation’ has come into its own this season as the rightful companion to ‘The Office’; and ‘Community’ is one of the freshest comedies on any network and a solid foundation for Thursday night.”

“The Office” (Thursdays, 9-9:30 p.m. ET) is delivering a 4.0 rating, 10 share in adults 18-49 and 7.7 million viewers overall through the season’s first 25 weeks, ranking in primetime’s top 15 in adults 18-49 and top five in adults 18-34 (excluding NFL pre- and post-game shows), making it NBC’s #1 scripted show in both categories. “The Office” is the #2 most upscale primetime show on ABC, CBS, NBC, Fox or CW in terms of its concentration of adults 18-49 living in homes with $100,000-plus incomes, behind only NBC’s “30 Rock.”

Season to date, “Parks and Recreation” (Thursdays, 9:30-10 p.m. ET) is delivering a 2.8/7 in 18-49 and 5.5 million viewers overall. With its move this season to Thursday’s 9:30 p.m. ET half-hour, “Parks and Recreation” is up versus last season by 17 percent in adult 18-49 rating (2.8 vs. 2.4) and up 9 percent in total viewers (5.5 million vs. 5.1 million). In the valuable adult 18-34 demographic, “Parks and Recreation” is NBC’s #2 scripted series and ranks in the top 20 overall with a 3.2 rating.

“Community” (Thursdays, 8-8:30 p.m. ET) is averaging a 2.1/6 in 18-49 and 4.7 million viewers overall, continuing to deliver solid numbers in a time period that includes competition from Fox’ “American Idol,” CBS’s “Big Bang Theory” and ABC’s “Wipeout.” “Community” is also one of the most upscale primetime series on ABC, CBS, NBC, Fox or CW, with a top-15 ranking in its concentration of adults 18-49 living in home with $100,000-plus incomes.

One of television’s most critically acclaimed comedies, “The Office” has been nominated for the Emmy Award for Outstanding Comedy Series every season and won the award in 2006. Its ensemble has also been nominated every season since 2006 for the SAG Award (winning in 2007 and 2008) and was also nominated for a Golden Globe Award for four consecutive seasons (2007-2010). The series received the George Foster Peabody Award in 2006.

In a recent cover story, Entertainment Weekly proclaimed that “Parks and Recreation” is “TV’s smartest comedy.” GQ magazine also enthused: “Look: This is the best comedy going right now.”

TV critics continued to rave about “Community” this season. Time magazine’s James Poniewozik wrote: “Episode by episode, ‘Community’ makes some of the best half-hours on TV.” “‘Community’ is a fantastical, dreamlike jewel-box of a show?.it’s a pretty amazing ride?” Also, TV Guide’s Matt Roush called the series, “TV’s most adventurous and unpredictable sitcom.”

In addition, both “Parks and Recreation” and “Community” were honored last week by the prestigious William S. Paley Festival.

From Deedle-Dee Productions, Reveille and Universal Media Studios comes “The Office,” the hilarious documentary-style look into the humorous and sometimes poignant foolishness that plagues the world of 9-to-5 based on the award-winning BBC hit. A fly-on-the-wall “docu-reality” parody about modern American office life, “The Office” delves into the lives of the workers at Dunder Mifflin paper supply company in Scranton, Pennsylvania. Regional manager Michael Scott (Golden Globe winner and Emmy nominee Steve Carell, “Despicable Me,” “Date Night”) is the boastful tour guide.

Novak (“Inglorious Basterds”), Ed Helms (“The Hangover”), Leslie David Baker (“Malcolm in the Middle”), Brian Baumgartner (“Arrested Development”), Kate Flannery (“The Heir Apparent”), Mindy Kaling (” No Strings Attached “), Angela Kinsey (“Tripping Forward”), Paul Lieberstein (writer, “King of the Hill”), Oscar Nu?ez (” The Proposal “), Phyllis Smith (“Arrested Development”), Creed Bratton (former member of The Grass Roots), Craig Robinson (“Hot Tub Time Machine”), Ellie Kemper (“Important Things with Demetri Martin”) and Zach Woods (“The Other Guys”). “The Office” is executive-produced by Ben Silverman, Greg Daniels, who developed the series for American audiences, Ricky Gervais, Stephen Merchant, Howard Klein and Paul Lieberstein.

Named the #1 TV Show of 2010 by New York magazine, “Community,” is a smart, exuberant comedy series about a band of misfits who attend Greendale Community College. At the center of the group is Jeff Winger (Joel McHale, “The Soup”), a fast-talking lawyer whose degree has been revoked. Winger forms a study group who eventually learn more about themselves than their course work. Also among the series stars who comprise the group are comedy legend Chevy Chase (“Fletch”), Gillian Jacobs (“The Book of Daniel”), Yvette Nicole Brown (“Rules of Engagement”), Danny Pudi (“Greek”), Alison Brie (“Mad Men”), Donald Glover (“30 Rock”) and Ken Jeong (“The Hangover”).

“Community” was created by Dan Harmon (“The Sarah Silverman Program”) who serves as executive producer with Russ Krasnoff (“The Soloist”), Joe Russo (“Arrested Development”), Anthony Russo (“Arrested Development”), Garrett Donovan (“Scrubs”), Neil Goldman (“Scrubs”) and Gary Foster (“The Soloist”). The series is a Krasnoff Foster Entertainment, Harmonious Claptrap, Russo Brothers, Universal Media Studios production in association with Sony Pictures Television.

“Parks and Recreation” — from Emmy Award-winning executive producers Greg Daniels (NBC’s “The Office,” “King of the Hill”) and Michael Schur (NBC’s “The Office,” “Saturday Night Live”) — is a hilarious ensemble comedy that landed on dozens of critics’ “Top 10” lists in 2010. It follows Leslie Knope (Emmy Nominee Amy Poehler, NBC’s “Saturday Night Live,” “Baby Mama”) a mid-level bureaucrat in the Parks and Recreation Department of Pawnee, Indiana, and her tireless efforts to make her quintessentially American town just a little bit more fun.

Leslie’s office mate is Tom Haverford (Aziz Ansari, “Human Giant,” “Scrubs”), a fashion-obsessed wannabe player while Leslie’s boss, Ron Swanson (Nick Offerman “Children’s Hospital”), hates the very government he works for. Rounding out the characters are Leslie’s best friend Ann (Rashida Jones, “I Love You, Man,” “The Office”), her ex-boyfriend Andy (Chris Pratt, “Everwood”), and Ron’s assistant April (Aubrey Plaza, “Funny People”). Also working in the parks department are Donna (Retta, “It’s Always Sunny in Philadelphia”) and Jerry (Jim O’Heir, “Castle”). In addition, the show features state auditors Ben Wyatt (Adam Scott, “Party Down”) and Chris Traeger (Rob Lowe, “Brothers and Sisters,” “The West Wing”), who were introduced at the end of the second season.

“Parks and Recreation” is a production of Deedle-Dee Productions, Fremulon, 3 Arts Entertainment and Universal Media Studios. Along with Daniels and Schur, Howard Klein (“The Office”) and David Miner (“30 Rock”) also serve as executive producers for the series.
