Since GKIDS is an American company formed in 2008, your have to consider what the average American in 2008 thought about anime. And for the 99% of them, they are cartoons. And cartoons are for children. Do that explains that.

Ironically, in Japan, there isn’t much of a distinction between anime and cartoons. They’re both called anime, which is just short for animation or animated work. So for the Japanese, Tetsujin 28, Berserk, Disney’s Sleeping Beauty, and Shrek are all “anime.”
