Ratings aren't amazing, but NBC is showing confidence in most of its Monday lineup, providing a full-season pickup for freshman drama "The Event," with "Chuck" expecting a similar call any minute.

"The Event," which took over "Heroes" spot on NBC's schedule starring Jason Ritter, Laura Innes and Blair Underwood, premiered to a strong 6.8 rating/10 share on Sept. 20, some of the network's best numbers in that timeslot in a long time, and almost doubling the audience of its "Chuck" lead-in.

However, audiences have drifted away quickly from the show, its Oct. 11 episode picking up just a 3.9/6, according to Fast National ratings from The Nielsen Co. That was a drop of 43 percent from the premiere, and is pushing numbers back to where NBC was with "Heroes" and "Trauma" last year in the same timeslot.

But because of the strong series premiere, "The Event" is averaging a 5.2/8 after four episodes, nearly 63 percent ahead of what NBC did in the timeslot last year, and it remains NBC's best-rated show on Mondays -- if not by much.

One thing that's helping "The Event," of course, is that the show is an in-house production. That means alternative viewing methods on Hulu, iTunes, later DVD collections and the like, will increase revenue for NBC, thus convincing the network to continue giving it a chance.

NBC also ordered full seasons of "Law & Order: Los Angeles" and "Outsourced," two other new shows on NBC's schedule, despite the fact that "Outsourced" was one of the Big Four networks' lowest-rated series last week.
