Nickelodeon it is the 2020s era...which means you must have an epic and historical cartoon (or 2 if ya can) that causes a positive impact on something in media history
1990s: Rugrats and Spongebob Squarepants (made Nickelodeon a top tier name)
2000s: Invader Zim (dark humor for the whole family occurring way too early in the world...but showed it can work for children), The Adventures of Jimmy Neutron: Boy Genius (a CGI show that was actually good, proving that high quality CGI shows can happen and be beneficial to a business...plus it be cheaper than hand drawing), and of course Avatar: The Last Airbender (as if anything needs to be said about them...like...come on y’all)
2010s: The Legend of Korra (brought the LGBT community into something for kids and showed that it can work, leading the a plethora of other family programming to do the same thing but continue to improve upon what Korrasami started, and went beyond expectations with dark themes like suicide and depression), and TMNT 2012 (CGI wise improved on what Jimmy Neutron started, but also rejuvenated the entire franchise, managed to further push getting away with more dark themes like Avatar, kicked the door fully for more crossovers with other properties...mainly Batman, Power Rangers, and Smite, and became Nickelodeon’s 2nd biggest franchise property behind Spongebob and ahead do Avatar)
so...ViacomeCBS in 2021...time for you to make Kamp Koral or Garfield the next megastar of your top network
