Many shows have fallen this year...cancelled or ended. Not that this doesn't happen every year...
Anyway, here is a list of some of the shows that are done this year. Several I will miss, others I'm glad to see done, and still others I never cared about.
Law & Order
The Tonight Show with Conan O'Brien
May the New Year bring worthy and lasting shows.
Hope your holiday is as bright as mine has been :)
