Warner Bros. and MGM and of course Disney made most of the popular cartoon stuff made in the US. Also Hanna Barbara did all back in the old days. Everything is gone global now, but most of the animation I watch now says it is made in Japan. Isn't Dexter's Lab and Samaria Jack and even Power Puff Girls all animated in Japan. How many popular cartoons are made/drawn in Hollywood  now? Maybe The Simpsons or King of the Hill, I don't really know for sure.  What's interesting though is now animations and movies can be peiced together from all over the world. It's hard to say where it's made exactly.  I think Japan can say they make there own anime and cartoon stuff. I don't know if we/US even make that much animation stuff anymore. Hollywood contracts it all out to Japan who it seems to me is the leader and place to go for animation making now. I rarely see anything that doesn't say it's not. I watch the old reruns and drive antique cars to get the real made in USA experience.
