Here are The CW’s renew/cancel standings for week 31 of the 2017-18 season.
|Show||Status||18-49 rating||Renew/Cancel Index|
|The Originals||Final season||0.4||0.2|
|iZombie||🐻 🐻 🐻 🐻||0.24||0.04|
|The 100||🐻 🐻 🐻||0.4||0.2|
|Life Sentence||🐻 🐻||0.15||-0.05|
|Jane the Virgin||Renewed||0.24||0.04|
|Legends of Tomorrow||Renewed||0.49||0.29|
The CW aired 15 scripted shows across a 10-hour schedule this season. In 2018-19, the network will add two additional hours of primetime on Sundays, a 20 percent increase in available space.
It stands to reason The CW will want more shows to fill that space across the full season — 20 percent more shows would be 18. Ten CW series have already been renewed, one (“The Originals”) is in its final season and two (“Valor” and “Life Sentence”) likely aren’t coming back.
All of which is a lot of preamble to say that “iZombie” is getting a bump up to likely renewal. The CW is going to need extra inventory, and “iZombie” has proven to be a decent utility player for the network.
The Bear is somewhat inclined to mark “The 100” as a likely renewal too, but since it just debuted he’ll save judgment for another week.
Note: All of The CW’s shows are produced by network owners CBS and Warner Bros., so ownership of series isn’t a factor.

The Renew/Cancel Index is the amount above (or below) a replacement-level rating — i.e., the expected adults 18-49 rating of an emergency fill-in show should a series be canceled. For the 2016-17 season, replacement level is a 0.7 same-day rating in adults 18-49 for the Big 4 networks and a 0.2 for The CW. (Read more here.) The index number is taken by subtracting 0.7 (or 0.2) from a show’s average same-day rating.
Friday scripted shows (denoted with an “F” above) on the Big 4 have average ratings about 30 percent lower than those of other nights, therefore their ratings are multiplied by 1.43 (1/0.7, or 70 percent) before subtracting the replacement-level number. There is little variance for The CW on Friday, so the multiplier is not used.
Shows that have ended their seasons have their R/C Index number frozen at the point of their final episode.
(O) – Owned: All other things equal, shows owned by studios affiliated with their networks have a better shot at renewal than those from outside producers.
