The CW has announced that they are canceling Frequency and No Tomorrow, both after only one season.
Both shows only averaged 0.26-0.27 adults 18-49 Live+same day rating for their 13-episode seasons. This was the first time in the channel's history that a new fall series, let alone two, didn't get a second season order.
The CW already has plenty of new shows in the pike, with execs liking 6 new pilots, on top of 9 existing scripted series already being renewed for next season.
