Excluding its Thanksgiving-night episode, “Arrow” hit a low last week, and as the Bear noted earlier in the season, the series is starting to look a little bit long in the tooth, ratings-wise.
Doesn’t matter. “Arrow” is still very likely returning next season, even if it’s only a reward for launching the comic-based world that takes up 40 percent of The CW’s schedule in any given week.
As the Bear said in November, “Arrow” is clearly closer to the end of its run than to the beginning. But that end is not coming this season.
Note: All of The CW’s shows are produced by network owners CBS and Warner Bros., so the (O) designation (see below) is immaterial.

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.
