NBC announced today its 2009-2010 schedule featuring more original programming than ever before and a shared time-period strategy around NBC's Olympics platform that, along with The Jay Leno Show (Mondays-Fridays 10-11 p.m. ET), allows the network to broadcast all-new content year-round.

In addition, NBC issued renewals to Law & Order and Chuck as part of its strong slate of new and returning shows announced recently at the network's highly successful Infront.

"NBC has picked up more scripted shows than last season even with The Jay Leno Show at 10 p.m.," said Ben Silverman, Co-Chairman, NBC Entertainment and Universal Media Studios. "We're incredibly excited about our new and returning series and have more comedy programming than anyone else, as well as two of the most buzzed about new shows, Community and Parenthood. We can't wait for the fall."

"We are extremely proud to introduce these strong new series to NBC's schedule next season in strategic timeslots that position them for success," said Angela Bromstad, President, Primetime Entertainment, NBC and Universal Media Studios. "They join some of the highest quality returning shows on television, which will serve as a strong foundation to the new schedule. I think viewers are going to be happy to see this lineup of great new shows that will truly fit the NBC legacy of quality, culturally defining shows."

NBC's shared time period strategy will kick off this fall on Mondays with the premiere of Heroes (8-9 p.m. ET) continuing with all originals before Chuck assumes the time period after the 2010 Winter Olympic Games, which will be a powerful launching platform with its broad, female appeal and strong ratings as the most-watched event of the year. Using NBC Sunday Night Football's potent promotional platform, the new high-octane drama Trauma will debut Mondays (9-10 p.m. ET) with the epic event series Day One taking over the time period following the Olympics.

NBC's successful The Biggest Loser series continues Tuesdays (8-10 p.m.) and will help launch the new Wednesday lineup this fall, with the new family drama Parenthood debuting (8-9 p.m. ET) and the new hospital drama Mercy assuming the time period post-Olympics. Law & Order: Special Victims Unit will air 9-10 p.m. ET following Parenthood.

NBC's Thursday marquee comedy night will begin with the only live comedy between 8-10 p.m. on any network, Saturday Night Live Weekend Update Thursday (8-8:30 p.m. ET), followed by Parks and Recreation (8:30-9 p.m. ET), The Office (9-9:30 p.m. ET) and the new comedy Community (9:30-10 p.m. ET). After Saturday Night Live Weekend Update Thursday completes its multi-week run, Community will move to 8 p.m. and 30 Rock will debut at 9:30 p.m., enabling NBC to feature more original comedy than ever before.

On Fridays in the fall, the enduring drama Law & Order will return for its record 20th season (tying Gunsmoke as the longest running drama series in primetime) and will lead off at 8-9 p.m. (ET) while Southland follows at 9-10 p.m. (ET), building a great crime block.

Saturdays will be a showcase for Dateline NBC (8-9 p.m. ET) and encore episodes of Trauma (9-10 p.m. ET) and Law & Order: Special Victims Unit (10-11 p.m. ET).

Football Night in America (7-8:20 p.m. ET) and NBC Sunday Night Football (8:20-11 p.m. ET) - the number one show of the fall -- will return on Sundays in the fall with a fan-pleasing schedule of games to round out the fall season.

Utilizing the compatible demographics provided by the Olympics, NBC will launch the premieres of The Marriage Ref from executive producers Jerry Seinfeld and Ellen Rakieten on Sundays (8-9 p.m. ET) and the third season premiere of Celebrity Apprentice on Sundays with two-hour editions (9-11 p.m. ET). In addition, the new comedy 100 Questions will debut on Tuesdays (9:30-10 p.m. ET) following a 90-minute edition of The Biggest Loser (8-9:30 p.m. ET).

And coming in the summer, NBC will telecast all original episodes of The Jay Leno Show, Friday Night Lights, America's Got Talent, Breakthrough with Tony Robbins, Dateline NBC, with additional programs to be announced later.
