Chuck managed a preliminary 2.1 adults 18-49 rating last night, against repeat competition on both CBS and Fox. That’s up from last week’s 1.9 rating, but have the show’s ratings taken a mortal hit? Is it now just a matter of time before Chuck slips beneath the TV waves?

Last week’s uptick to a 2.7 adults 18-49 rating for Parenthood is a level that would certainly get the show renewed. Question is, can it hold on to something near that level until NBC makes up its mind for next fall? It could get the benefit of a Southland “squeeze”, where renewal is announced prior to subsequent ratings declines.

Note that Chuck and Parenthood’s ratings averages contain only new episodes, most of NBC’s fall shows have many repeat episodes factored into their ratings averages.

Some would put Heroes on NBC’s bubble. For me, its final show ratings of 2.2, 2.1, 1.8, 1.9, 2.0, 2.0 say its a goner, even on NBC.

As horrible as the situation is, NBC will try something new other than keeping the ratings hulks Trauma and Mercy.

This is a breakdown of NBC scripted shows and their renewal and cancellation prospects. Here are links to the other networks:


The Renew/Cancel Index is a show’s Season To Date adults 18-49 rating divided by its network’s Season to Date average 18-49 rating (in NBC’s calculation  I have removed the ratings effects of the weeks that included the Winter Olympics). If a show’s season to date 18-49 ratings average equalled its network’s 18-49 average, the show would have an Index of 1.00. Without special factors, scripted shows that were more than 10% below their network’s average are typically canceled by the end of the broadcast primetime season.

Factors that could cause a show to be renewed with a well below average Index:

  • (F) -Fridays: Shows airing on Fridays have been renewed with significantly lower than average Indexes.
  • (S) – Syndication: Shows nearing syndication (66-88 episodes), often have economic factors that trump ratings leading to renewal.
  • (T) – Third Party: Shows that have a portion of their cost underwritten by a 3rd party can be renewed with substantially lower ratings.
  • (P) – Produced by the network’s production company – For shows on the bubble, being produced by the network’s corporate production company can be a survival advantage. For real losers, it’s unlikely to help.
