I would just say The Mentalist <3,Criminal Minds,and Royal Pains ...And an german show that no one knows anyway xD(For whom whom wants to know:Mein Leben Und Ich )
Besides that ...not really anything :p
A LOT. Pretty Little Liars, Gossip Girl, How I Met Your Mother, 2 Broke Girls, Suburgatory, One Tree Hill, Revenge, Modern Family, Grey's Anatomy, The Vampire Diaries, The Secret Circle, etc :)))
I love The Big Bang Theory, How I Met Your Mother, Supernatural, Sanctuary, Two and a Half men and Glee thogh lately some shows have been sorta bland :/
What about Heroes? Not really addict but started recently online and got to the third season. It's nice :D And of course Deseperate Housewives, hahaha really funny to watch. And than all the cartoons like Avatar, phineas and ferb, south park, the simpsons and so on
I rarely watch TV, but the shows I am addicted to would include: The Big Bang Theory, Chuck, Vampire Diaries and True Blood.
As for older shows I'm a Star Trek nerd <_<............>_>
