Maya Rudolph of NBC's "Up All Night"

*Today brings good news for Russell Hornsby and Maya Rudolph.

Their respective shows for NBC – the fairy tale drama “Grimm” and motherhood comedy “Up All Night” – both received good news from the network. “Grimm,” starring Hornsby as a homicide detective, scored a full season pickup, while “Up All Night,” featuring Rudolph as a self-absorbed-yet-well-meaning talk show host, got an order of two additional episodes, bring the total number of episodes to 24 for the first season.

The Wednesday night comedy, which last week drew 4.8 million viewers and a 1.9 in the advertiser-coveted adults 18-49 demo, in an effort to protect the series from ratings erosion, will shift to Thursday beginning Jan. 12, where it will air after “The Office,” according to The Hollywood Reporter.

Meanwhile, “Grimm” has been anything but grim for NBC on Fridays.

“We are very pleased to be making a full-season commitment for ‘Grimm,’” NBC Entertainment chairman Robert Greenblatt said in announcing the news. “This series is turning the traditional procedural drama on its head and is attracting a loyal following for us on Friday nights. We love where it’s going creatively and we’re excited to deliver more episodes to our audience.”

Like “Up All Night,” NBC is moving the series to more fertile ratings ground — from Fridays at 9 p.m. to Thursdays at 10 p.m., beginning Dec. 8.

Since launching amid heavy competition, “Grimm” has averaged a 2.3 rating/7 share in the advertiser-coveted adults 18-49 demographic, drawing 6.9 million viewers, according to Nielsen.
