The 100 [The CW]
Yet another The CW series has earned a renewal for the 2017-18 season.
Three days after picking up “Riverdale” for a second season, The CW ordered a fifth season of “The 100.”
The renewal comes five episodes into the show’s fourth season.
In renewing “The 100,” The CW has officially made a decision on all current scripted series. “The Vampire Diaries” and “Reign” are both concluding this year, while the remaining slate will be back in 2017-18.
