Because Dragonball Z was and still is the most watched animated series in the history of the world, that means 2 or more things, let's do the math...

If Dragonball Z is the most watched cartoon in the history of the world...

That would mean that internationally, Dragonball Z has the largest audience viewership overall this side of YouTube, probably partially BECAUSE OF YouTube.

Therefore, if we do the math, we can deduce from the facts by putting 2 and 2 together, and we realize, because DBZ is anime, Japanese television animation (NOT American) has the largest viewership internationally, in the entire world. Anime often doesn't get the largest ratings in America, but because of the fact that anime has such a large audience base worldwide, INTERNATIONALLY, not just nationally, that would make anime the most popular form of television animation ANYWHERE IN THE WORLD, IN GENERAL. There ARE NOT American animation conventions, other than as a novelty sideshow at Comic-Con and the like.

So, thereFORE, if you want to create the next GLOBAL FRANCHISE (not just Family Guy or The Simpsons or SpongeBob, or Disney), there are some elements you need to be familiar with that shows like Dragonball Z mastered. First of all, the only shows that SELL to an international audience are in fact the only cartoons that don't Lecture or or Talk Down To a Global International Audience. One of the least pleasant elements of American Animation that can really make an American animated series BOMB internationally, especially in Asia, is condescending and racist racially based stereotypes. Yeah, racism. Not gonna go over well in the international world selling market. Animation with real international world credibility has always promoted diversity and tolerance and compassion. Racist and Stereotypical American animation and TV writing and acting and design is JUST THAT: Ignorant American shit. And that's Exactly how overseas viewers see it too. But you don't have to take MY word for it.

A a show with a Worldwide Global Franchise Audience in America, Europe, and Asia (among other places) needs to speak a global visual iconographic story language, and that language is:

Action. Adventure. And a sense of anime aesthetics (i.e. a visual and literary influence) inspired by whichever animes and mangas the creator and creative production team behind the show like.
