American Dad! is created by Seth MacFarlane, of Family Guy fame.

I live in Europe, and I've heard of it. :p

Yeah, I think any american/canadian that's a Family Guy fan is aware of this show, which I believe started last year.

I live in UK and I've heard of it – started on our TV last autumn
It rocks :)

Last week they also mentioned Google in CSI Miami.

they broadcast it in Sweden and in Lebanon.

Live in Houston; I've heard of it, though I've never seen it. I did happen to see the creators talk about it, and they described it thus: it's a satire of American conservatives. The creators figure that American liberals will find it hilarious, and conservatives won't be smart enough to know they're being made fun of, and like it too.

Meh. I'll stick with The Daily Show.

It's mentioned in a lot of shows, so I wonder what makes the American Dad bit special?
