Not sure about ‘aldut humor’, that would probably cross a line for networks image.

Avatar Korra was definatly more for teens than ATLA.

Ben 10 also grew up with audience, making them teens and eventually rebooting the IP to milk the next generation.

Spongebob’s hidden adult humor pretty much disapeared as the years went on. (Doubt we"ll ever see something like the panty raid again).

Teen Titans go is the opposite, taking a more teenage show and making it for younger kids.
