Ready or not, spring will determine the fate of several CBS shows.

Things are beginning to shake out for several shows between the ratings and CBS’s mid-season schedule shuffling. The Defenders slim chance at renewal is quickly approaching zero, and it’s looking more and more like both of the CSI spin offs are teetering towards the bone yard. I still see CBS holding its nose over The Good Wife’s ratings with one eye on its Emmy and keeping it around for another season, and the temporary move of Blue Bloods to Wednesday indicates that CBS would like to keep it around as well, but we’ll have to see how the spring ratings turn out.

Take a good look at the table above, it’s the last time I’ll post a Renew / Cancel Index using Fall 2010 ratings for CBS shows.

Starting next week and going forward, the new Renew / Cancel Index tables will use only the ratings for shows on 1/3/11 and later.

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.

This post will always be available on the site, you can bookmark it, but I’ll have a link to it in all the spring posts as well.

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.
