Our Renew / Cancel Index predicts potential renewal or cancellation for scripted broadcast primetime shows by the end of the 2010-11 season in May, 2011. (includes results from January 3 – May 15, 2011):

Program Status Renew/ Cancel Index
Hellcats cancelled 0.71
Life Unexpected cancelled 0.80
Gossip Girl renewed 0.86
One Tree Hill renewed 0.89
90210 renewed 0.90
Nikita renewed 0.91
Supernatural (F) renewed 1.09
Smallville (F) final season 1.11
Vampire Diaries renewed 1.53

The CW only gave the Renew / Cancel Index eight trips to the plate this season, but it made the most of them, batting 1.000 on the CW’s renewal and cancellation predictions. Late season drops by both One Tree Hill and Nikita shaved the confidence levels on their renewals, but the Index stayed on the good side of both calls.

With that the Index bids the 2010-11 CW season adieu, there will be no more CW Renew / Cancel posts until September, but expect a general post in the  next couple weeks on some potential changes for next season’s Renew / Cancel Index.

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.
