Resetting the CBS Renew/Cancel Index to use only shows airing on or after 1/3/11* doesn’t help us much, yet.

Many of the shows with questions over their fate didn’t air last week, and because of that the CBS scripted show average gives an incomplete picture for the fate of its shows. I’ve included the Index calculations for the shows in the table above, but have left out any new status until more of the scripted shows in the line up have at least one episode aired in the spring.

*Why do that?

In previous seasons, comparing the season ratings averages for shows that began in the spring to those that began in the fall proved a bit apples to oranges because the overall lowered spring ratings (partially caused by Daylight Savings Time as well as a variety of reasons) tended to understate the position of shows that began in the fall. When tested on last season’s ratings, beginning a new Index after New Year’s seemed to correct that apples to oranges comparison problem.

The Renew/Cancel Index is the ratio of a scripted show’s new episode adults 18-49 ratings relative to the new episode ratings of the other scripted shows on its own network. It’s calculated by dividing a show’s new episode Live+Same Day adults 18-49 average rating by the Live+Same Day new episode average of all the new scripted show episodes on the show’s own network. The network’s average ratings in the calculation are not time weighted (ex. hour long shows are not weighted twice what 30 minute shows are).

(F) -Fridays: Shows airing on Fridays were renewed with significantly lower than average Indexes.

How would the Renew / Cancel Index Have Done Predicting Last Season’s Scripted Show Fates? While the methods used have changed slightly from past seasons check out how the Renew / Cancel Index would have predicted renewals and cancellations from the 2009-10 broadcast television season.
