Family Guy, Futurama, and American Dad are the only shows that are not cartoon network originals, there are a plethora of other shows that they run.
Inuyasha, Cowboy Bebop and the other asian stuff are not originals. Looking at the list I can\'t pick all of the Cartoon Network originals but I do feel like they tend to be low-budget productions. That is not necessarily a bad thing, if the writing is funny then the animation does not need to knock you off your feet.
