April 2, 2018
The CW announced today that The Flash has been renewed for a fifth season. The action drama continues to be one of the network's strongest-performing series, with ratings that consistently top its fellow superhero-based entries.
It is unknown if Season 5 will consist of the typical 23 episodes it has received in each season thus far, but even with a shorter order, the show will reach the 100-episode milestone when it returns.
Along with The Flash, The CW renewed all of its other DC universe programs today. Also picked up for the 2018-2019 season are Arrow, Supergirl, Legends of Tomorrow, and newcomer Black Lightning.
