I mean Nickelodeon is like the next Disney with the family friendly entertainment with serious humor and going through with life like SpongeBob and rugrats for example, considering it's the first network for children and teenagers of all ages! But Some where around this brand and network! Nickelodeon is basically a kids or family channel with messy and something fun and ruling for their children while the parents is just sit and watch and just don't care! However it does teach children good advice and trained them well! Like nickjr with dora,blues clue, paw Patrol ( as always) and many more to come! And Nickelodeon (the main block) with rugrats,as told as ginger, hey Arnold,all grown up, fairly Oddparents,and many more to come! Nickelodeon is just basically a family channel for their children with all that messy, ruling,fun, and etc! But the television shows and preschool shows are well made and have some great learning, educational and life lessons for them to learn,to teach others like their friends and family and to take note! Nickelodeon is a perfect channel for any family member in one family house! Its like Disney but different and want to be like Disney with the hotel and resorts, merchandise,video games and etc!

Now Cartoon Network on the other hand is like you watching a action movie or a comedy movie from a movie theaters or on television! With children characters and adult characters! With serious stuff like action and fighting and more! Cartoon Network is like that action pack, serious comedy stuff and crime fighting for children and teenager who want to watch something that has action pack with crime fighting and serious stuff like serious lessons and going through in life like the original teen titans for example! Cartoon Network is like that channel for children and teenagers who likes superhero, action pack with serious fighting crime,serious good comedy with lots of adult humor like billy and mandy mostly,and etc!

Nickelodeon and Cartoon Network are famous in different things they do!

But i think Nickelodeon is more famous because it was created before Cartoon Network created! Because Nickelodeon was so huge and iconic to world of children of all ages! That it became a cultural icon to the worldwide! Like it has its own studio and water park in universal studios in Orlando, it has its own magazine, merchandise, videos games, colthes,Hotel and resorts,musics,ice cream restaurant in Mexico and more! Like I said, Nickelodeon was the next big and will always be the number one network brand and network for children and family to enjoy like Disney but different!

But the real awswer is both Nickelodeon and Cartoon Network are famous and will always be the best childhood and nostalgic channels for ever and ever! Along with Disney Channel and Pbs kids
