Our Renew / Cancel Index predicts potential renewal or cancellation for scripted broadcast primetime shows for the 2010-11 season (results through November 29, 2009):

  • Likely To Be Canceled By May, 2010
  • Some Danger Of Being Canceled By May, 2010
  • Likely to Be Renewed For The 2010-11 Season
Program Renew/ Cancel Index
The Beautiful Life: TBL (P) 0.49*
Melrose Place (P) 0.58
90210 (P) 0.81
Smallville (F), (P) 0.89
Gossip Girl (P) 0.90
One Tree Hill (P) 0.91
Supernatural (S), (P) 0.99
Vampire Diaries (P) 1.40

Although fan blindness is so severe at times, I wonder why I try to get in front of it, the headline of the post is for Melrose Place fans who fail to recognize that:

1. I do one Renew / Cancel post per broadcast network, per week.

2. Melrose Place is the only scripted show currently on the CW likely to be canceled at the end of this season.

3. Headlining these posts with any of the other shows that seem certain to be renewed is likely to be slumber inducing. Although I did that, twice.

Note that Supernatural, Vampire Diaries and Smallville appeared in their regular timeslots in the past week, but were designated “specials” by the CW, so those episodes are not included in any season averages. That’s a somewhat arbitrary distinction, but since its the convention, I am following it.

*I have frozen The Beautiful Life’s Index at its value the week of cancellation.

This is a breakdown of CW 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. 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 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.

While I initially tried to designate shows with “plum” timeslots, I think that’s hard to make that call at this point in the season. It’s likely still a factor, but will have to be an “after the fact” call.
