Mili Vanili had a cartoon? Faking their singing is one thing, but making a cartoon? WTF? Egomaniacs. Oh ya, I forgot about COPS.
I think COPS and Captain Planet both aired in 88. My memories are a little fuzzy here...possibly Fantastic Max and that Mili/Vanili cartoon. I'm sure I'll think more.
The original Ninja Turtles cartoon first aired in December 1987. I would say as soon as it came on it dominated. I remember watching it in 1988....when I was 2. I was hooked immediately.
