The CW announced today that Supergirl has been renewed for a fourth season. Airing on Monday nights, the series draws fairly consistent ratings that place it in the middle of the pack compared to other shows in the network's lineup.
The action drama has fared well since its move to the network from its original home on CBS. Being on The CW also allows it benefit from crossover episodes with other shows from the DC Comics universe, which have proven to give it a significant ratings bump.
All five of its DC superhero series were picked up today by The CW. Fans can look forward to more Arrow, The Flash, Supergirl, Legends of Tomorrow, and Black Lightning in the 2018-2019 television season.
