NBC has renewed three more of its Thursday-night comedies - 30 Rock (9:30-10 p.m. ET), The Office (9-9:30 p.m. ET) and the freshman series Community (8-8:30 p.m. ET) for the 2010-11 season. The returning programs join the previously announced Parks and Recreation (Thursdays, 8:30-9 p.m. ET) that also will return for next season.

The announcement was made by Angela Bromstad, President, Primetime Entertainment, NBC and Universal Media Studios.

"We are happy to give these early pickups to these critically acclaimed, incredibly funny comedies," said Bromstad. "As a result, we look forward to continuing our rewarding partnership with the respective creative teams and talented show-runners for '30 30 Rock, The Office and Community as they all consistently deliver quality shows."

First-year comedy Community is averaging a 2.7 rating, 7 share in adults 18-49 and 5.9 million viewers overall so far this season, with Community originals winning the time period among adults 18-34 and men 18-34. Since moving to the Thursday 8-8:30 p.m. (ET) half-hour on October 8, Community has improved the time period by 24 percent versus NBC's adult 18-49 average earlier in the season.

Currently in its sixth season, The Office is network television's #1 primetime scripted series among adults 18-34 and is NBC's #1 scripted series in the key demographic of adults 18-49. The Office regularly finishes #2 in its highly competitive time period in adults 18-49 ahead of CBS's CSI. The most recent The Office telecast on March 4 outscored ABC's Grey's Anatomy, marking the first time The Office has topped Grey's Anatomy head-to-head in adults 18-49. For the season through 23 weeks, The Office is averaging a 4.9 rating, 12 share in adults 18-49 and 9.4 million viewers overall, representing gains versus last season of 4 percent in 18-49 and 3 percent in total viewers.

Currently in its fourth season, 30 Rock is averaging a 3.4 rating, 8 share in adults 18-49 and 6.9 million viewers overall, with 30 Rock originals winning the time period among men 18-34 and men 18-49 despite airing opposite the concluding half-hours of ABC's Grey's Anatomy and CBS's CSI. 30 Rock is the most upscale comedy on broadcast primetime television when ranked by its concentration of homes with $100,000-plus incomes in its adult 18-49 audience.
