Brits, Irish, Aussies, Kiwis: What American sitcoms air where you are?

Which current situation comedies are popular now?
How I Met Your Mother, Two & A Half Men, Ugly Betty, etc.
Do you get the opportunity to see the US version of The Office? I’ve been a big fan of the original BBC series, but I find the US series pretty funny as well.
And what about older sitcoms? Which were popular in your country? M*A*S*H, Cheers, Frasier, Everybody Loves Raymond, Friends, etc.
I read somewhere that Seinfeld, which was enormously popular over here, fell flat with UK audiences.
So what comedies from here do people enjoy where you are?
Just curious.
