NBC has given early pickups to The Office, 30 Rock and The Biggest Loser.

According to Variety, renewals were announced Thursday afternoon during NBC's portion of the TV Critics Assn. press tour by new primetime entertainment prexy Angela Bromstad and incoming alternative topper Paul Telegdy.

"These renewals represent our faith in 'The Office' and '30 Rock' as they continue to represent the gold standard in acclaimed and award-winning series," Bromstad said.

During their exec session, Bromstad said that NBC still planned to shoot about the same number of pilots it did two years ago -- six dramas and four comedies.

Given the loss of five hours to Jay Leno, NBC wasn't expected to shoot as many pilots this year as it had in the past. In addition, last year, a post-strike NBC opted to greenlight most of its series sans pilots and suggested that it might continue to do so in the future.

Other news at NBC's session:

The Philanthropist is still on tap for a potential midseason bow -- which would make for an even busier spring for new NBC series.

According to Bromstad, movement on the show was delayed after thesp James Purefoy pulled a hamstring; he's since healed.

Bromstad said Lipstick Jungle isn't dead -- at least not yet -- but the long-term future of shows like Chuck and Life are also still uncertain.

Although the creative community has expressed concern over Leno's 10 p.m. berth, Bromstad said she's had "only positive conversations" with producers such as Dick Wolf (who's currently shooting the pilot Lost and Found for the Peacock).

But "no showrunner ever wants to see their show moved when it's performing well," she added.

The Peacock also announced that Conan O'Brien's last night on Late Night will be Feb. 20, with Jimmy Fallon taking over on March 2.

NBC's Amy Poehler laffer -- still untitled -- will air Thursdays at 8:30 p.m. (in place of Kath and Kim) starting April 9, while reality competish The Chopping Block will air Wednesdays at 8 starting March 11.

As previously noted, Kings -- originally slated for Thursdays -- will air on Sundays at 8 p.m. beginning in March.
