NBC TV Show Ratings for 2010-11 Season [as of 3/24/11]

Which NBC TV shows will be cancelled or renewed for the 2011-12 season? In large part this depends on a show’s ratings, particularly the 18-49 demographic. The lower the ratings, the more likely a show is to be cancelled.

Before we get to the season-to-date averages, here are the winners and losers from March 18th until March 24th — in terms of the coveted 18-49 demographic, as measured against the last original episode.

Week-to-Week Winners: The Biggest Loser 3.0/9 (+11.1%), Minute to Win It 1.2/4 (+20.0%), Law & Order: SVU 2.6/7 (+4.0%), Community 1.8/6 (+5.9%), Perfect Couples 1.6/5 (+33.3%), The Office 3.4/10 (+6.2%), Parks and Recreation 2.4/7 (+33.3%), and Outsourced 1.5/4 (+7.1%).

No change: Celebrity Apprentice 2.8/8 and The Event 1.2/3.

Week-to-Week Losers: Dateline 1.4/5 (Fri, -17.6%), Dateline 0.9/3 (Sun, -18.2%), America’s Next Great Restaurant 1.2/4 (-14.3%), Chuck 1.5/4 (-6.3%), Harry’s Law 1.6/5 (-11.1%), and 30 Rock 1.9/5 (-17.4%).

Below is a list of the regular NBC TV shows and their 2010-11 season average ratings to date. It only incorporates the ratings for original episodes that have aired this season, not repeats. The data is sorted by the 18-49 demographic averages, the group that advertisers will pay the most to reach and, therefore, the audience most important to the network. The “compared to” column reflects whether the demo average has gone up, down, or stayed the same since last week.

The closer a show is to the bottom of the list, the closer it is to being cancelled (if it hasn’t been cancelled already like Outlaw and Undercovers). If it’s closer to the top of the list, it’s more likely to be renewed. Shows that are in the middle (“on the bubble”) can be a little tougher to call. For example, Outsourced had a great start but is doing terribly now. Their future typically comes down to other factors like overall costs, contracts, who produces the show, and what new shows are on the horizon.

The list has been separated into two sections. Of the two, scripted programming is the most expensive. News and reality TV shows are less expensive to produce but the networks can’t program just news/reality (though they might like to since they are less of a financial risk).

It should be noted that Friday and Saturday nights are the least watched evenings of television so ratings for shows on those nights are lower. The networks understand this and take it into account. However, regardless of when a show is aired, its production costs remain the same. Ultimately, it must still be profitable enough for the network to keep ordering more episodes.
