When i was little i mostly watched rugrats, tom and jerry, sonic, Pokemon ! 
Just named a few, didn’t want to get embarrassed saying Barney . 
All this talk has prompted me to look for the old shows I used to watch on YouTube. And so far I’ve watched a few of them.
Looney Tunes
Captain Planet
Johnny Quest
Jetsons
Flinstones
Tom and Jerry
Swat Kats
Ed, Edd, n Eddy
Powerpuff Girls
Johnny Bravo
Cow and Chicken
I. M. Weasel
Courage the Cowardly Dog
well, there’re more but I can’t really think of them now.
Maybe those classic Disney’s ones (i.e. Aladdin, Pinocchio) and other Cartoon Network cartoons
ED,EDD, N EDDY ALL THE WAY!!!
