CW Renews Arrow, Supergirl, The Flash, and Legends of Tomorrow

The CW has announced that all four of its DC superhero shows will return for the 2017-2018 season. Arrow, Supergirl, The Flash, and Legends of Tomorrow were all renewed for next season, along with veteran series Supernatural, Jane the Virgin, and Crazy Ex-Girlfriend.

The CW has built its viewership thanks to the success of the DC shows, which aired on four different nights in the fall. After Arrow's strong debut in 2012, the CW created a shared "DC TV" universe with The Flash and Legends of Tomorrow in 2014 and 2015. The CW also acquired Supergirl from CBS (which owns half of the CW) after its first season. While Supergirl technically exists in a separate universe from the CW's other superhero shows, the title heroine has dimension hopped several times to crossover with those series.

When announcing the news, CW president Mark Pedowitz noted that the early renewals of the shows gave showrunners time to plan for next season. Premiere dates will be announced at a later time.

Notably, the CW has not announced renewals for iZombie and Riverdale, two comic book shows that haven't yet aired this season. Their fates will likely rest on the strength of CW's midseasons rating. The 100 and The Originals have also not yet been renewed for next fall.

The CW will also have some programming holes to fill next year. The Vampire Diaries and Reign will both end this spring, and rookie shows Frequency and No Tomorrow were not given additional episode orders, which could hint that the CW will not pick them up for a second season.

While the CW has a packed superhero slate, DC executive Geoff Johns recently hinted that another DC show will be announced soon, and rumors have persisted that the CW could add a fifth superhero show soon.
