Well, a new anime that is populair that I know of is Noragami. Kill la Kill is pretty populair as well, and it's new.

magi the kingdom of magic is a new one I have heard of so far

If u talk about 'famous', Naruto is the most famous anime I've ever known...
The anime that I think are old enough are Yu Yu Hakusho and City Hunter...
I also don't know any new one other than that weird anime, Space Dandy... I only know 2-3 upcoming anime shows....

The ones I know are:
One Piece
Naruto Shippuden
Fairy Tail
Bleach
Death Note
Fullmetal Alchemist: Brotherhood

A lot of fans say that Attack on Titan is worth watching. I haven't seen it myself, but I might soon.
