With "The Jay Leno Show" vacating five hours of primetime programming after February 11, NBC has announced a schedule for its 10 p.m. hours following the Olympics.
 
A mixture of scripted programming and unscripted shows will fill the 10 p.m. hours starting on March 1, with NBC shifting both "Law & Order" and "Law & Order: Special Victims Units" to 10 p.m. along with the new drama "Parenthood," as well as the Jerry Seinfeld produced "The Marriage Ref" and the familiar news magazine "Dateline."
 
"Law & Order" will move from Fridays to Mondays, with a two-hour premiere on March 1, settling into the 10 p.m. slot the following week. The new drama "Parenthood," formerly scheduled for Mondays at 9 p.m. (a slot that will be filled by "Trauma"), will go to Tuesdays at 10 p.m. The Wednesday 10 p.m. hour will be home to "Law & Order: Special Victims Unit," which will be pushed back from 9 p.m., with "SVU" encores holding down that 9 p.m. hour. Thursdays at 10, NBC will air "The Marriage Ref," from the aforementioned Seinfeld. That means that Fridays, "Dateline" will now air from 9 p.m. til 11. 
 
See? You thought it was going to be hard for NBC to fill all of that space.
 
NBC also announced that "Who Do You Think You Are?," a long-delayed genealogy show from Lisa Kudrow, will premiere at 8 p.m. on Friday, March 5. That series will air through til "Friday Night Lights" returns on April 31.
 
Also new to NBC's schedule is "Minute to Win It," a new game show hosted by Guy Fieri," in which contestants play a series of speedy, high-tension games with the chance to win a million dollars.
