CBS Fall

CBS is the network that has the least new shows as traditionally their shows do consistently well in the ratings. Among the new faces of the fall will be Jenna Elfman, Julianna Margulies, Chris O'Donell and Patricia Arquette (who is jumping ship from NBC).

NBC Fall

NBC's new schedule has less shows on prime-time as the network has decided to give Jay Leno the 10pm time-slot 5-night-a-week. As a result they only have 2-hours of scripted programming per night like the CW and Fox rather than CBS and ABC who continue with airing shows between 8pm-11pm.
With the Vancouver Winter Olympics commencing in February NBC also decided to divide its schedule into two.
