The 100 will end after its upcoming Season 7, creator Jason Rothenberg announced on Twitter Sunday.
The 100 is not being touted as being cancelled so much as ending on its own terms, with CW president Mark Pedowitz telling critics that Rothenberg always hoped to end the series after Season 7. In May, The CW renewed almost its entire lineup for the 2019-2020 season, aside from Jane the Virgin, Crazy Ex-Girlfriend, and iZombie, which were already scheduled to end after their most recent seasons.
