These charts incorporate the daily final CBS show ratings (reported by Nielsen) and are sorted by the 18-49 demographic. Network advertisers typically prize those viewers most and so will pay more to reach them. There’s lots of information that the networks take into consideration when cancelling or renewing a TV series but the ratings are the biggest factor. The higher the ratings, the better chance that the show will be renewed. And yes, they take it into account when a show airs on a Friday or Saturday night.
