Toons or Tunes?

I have been asking myself the same question all weekend.
Is it Looney Toons or Looney Tunes?

I googled it and all of the logos say Tunes so I'm kind of leaning toward that.
But wouldn't it make more sense to say Looney Toons as in cartoons?
I'm really confused so if anyone wants to help me out here it would be much appreciated.
