well if you consider when they first aired, cartoons were made for adults before they were kids if you consider adults watched tv more than kids. but they were probably considered more like "family shows" because households only had one tv. at some point, people realized cartoons could market to different age groups, and theres cartoons for literal kids teaching them things, and theres cartoons for just adults. i really dont see an issue with that but also, you dont have to watch adult humor shows as an adult, so
